How to Measure Bike Wheel Size with the Standard Method – Let’s start with a step by step guide on completing the standard method of bike wheel measuring:
Begin by propping your bicycle on its kickstand or against a wall so that it’s stable.Using a tape measure, place the bottom of the tape at the lowest point of the tire (on the ground) and measure in a straight line to the centre of the bike wheel to find your wheel radius (as shown in the image above).Multiply your wheel’s radius by two to find the wheel’s diameter.Now, measure the tire’s width by placing the measuring tape across the top of it.The numbers obtained are your standard measurements. Be sure to list diameter first, followed by the tire width.Bike wheel diameters are rounded to the nearest half-inch, so if your measurements are just over or under, round up or down to the nearest size.

What size is a 27.5 wheel?
Page 2 – Big Seven mountain bike with Racing Ralph 27.5″ tires 27.5 mountain bikes are which use a large volume that is approximately in diameter, 56 mm wide ( 56-584 / 27.5 × 2.25) on an ISO 584 mm rim.27.5 mountain bikes are also called tweeners, since it “fits between” the traditional 26-inch wheels and the newer “.
What is 700c wheel size?
Why are there different wheel sizes in road racing? The 700c (622 mm / 29 inches) is the most common wheel size for road racing. The 650b (584 mm / 27.5 inches) wheel size is used in specific areas. Each wheel size offers unique advantages for different kinds of riding.

What does “700c” mean? and get a €20 voucher Your cart is empty Add order note If you want to save money and have more fun, then converting your current bike to an electric bike is a great option. By wanglenco Oct 9, 2022 What does “700c” mean? 700c has been a very misunderstood term for a while now and we would like to clarify that for you.
- The most common issue with this term is confusing it with “700cc”.
- The 700cc is a term for motorcycles referring to their motor power.
- The words are very similar but the meanings are so different.
- The term “700c” is the tire size according to the French system.
- The “700” is stating the diameter of the bicycle tire and “c” is the width size of the tire.
However it’s not 700 millimeters it’s 633 millimeters. Also, another common mistake is that often riders confuse “c” with centimeters.700c’s c does not have anything to do with centimeters. The alphabetical order is coming from the old French system which starts with the letter “a” and goes through to “d”.
Size “a” is the narrowest and size “d” is the widest width size for a tire according to this system. Except “c” all other sizes dropped and have not been in use for a long time but “c” stuck because of widely used.Generally you can use 28mm to 35mm wide tires on the 700c rims. Another false assumption is that 700c and 29-inch tires are the same.
Unfortunately this is not true. “700c” has the same diameter with a 29-inch tire. However, the width of the 700c is narrower than a 29-inch tire. Riders think because their diameters are the same size, the width will also have the same size. If you fall into this mistake your tire unfortunately won’t fit into your rim.
Is a 29 inch wheel the same as 700C?
29′ (ISO size 622) is actually the same rim diameter as 700C, although most 29′ tires will not fit 700C road rims because they’re too wide.29′ tires are popular with mountain bikers; search for 29′ MTB.650B (ISO size 584) is used for some randonneur bikes and other specialized bikes.
Is 27.5 or 29 better?
Which mountain bike wheel size should you go for? – The decision really depends on your preferred riding style and your experience. As a general rule of thumb, you will benefit from 29 inch wheels if you’re a tall rider and enjoy bashing around your local trails.
Are 27.5 and 700c the same size?
Are 700c wheels the same as 29-inch wheels? – 29-inch and 700c: different names for the same thing. Warren Rossiter / Immediate Media Mountain bikes had their origin in the United States, and so their measurements are typically in inches, from frame size through to wheel size (the same goes for kids’ bike wheel sizes ).
Originally, as explained in our piece on mountain bike wheel sizes, they came with 26in wheels. That’s changed over the past decade, so the majority of modern mountain bikes now come either with 29in or 27.5in wheels. These two sizes are equivalent to 700c and 650b wheel sizes expressed in the European ETRTO wheel size designations and have the same bead seat diameters.
With that in mind, 29in mountain bike tyres should fit (in terms of diameter) on 700c rims and 700c tyres on 29er rims. Road and MTB freehubs may look similar, but the road standard is longer. Felix Smith / Immediate Media In reality, the best mountain bike wheels tend to have wider rim beds than road-going wheels, to support the much wider tyres (measured in inches rather than millimetres) found on mountain bikes, so the two are not quite interchangeable.
Is 27.5 a large bike?
What height is a 27.5 inch bike for? – 27.5 inch bikes are suitable for adults between 5’2″ and 5’10”. That said, adults of all heights can ride this wheel size. Some brands claim that 27.5″ wheels are especially useful for riders 5’7″ and under.
Which is bigger 27 or 700c?
How do I know if I can replace the 27 inch wheels with 700c wheels on my bike? You may or may not be able to make that conversion with your existing brake/frame combination. Your brakes will have to reach farther because a 700c wheel is a smidge smaller than a 27 inch wheel.
Depending on your setup, that may be possible. I’d recommend borrowing a 700c wheelset from someone to see if you can line it all up. If it all lines up, great. Purchase whatever 700c wheelset strikes your fancy. If not, you may be able to purchase brakes with a longer reach. Some older frames still won’t work with 700c wheels even with the longest brakes available.
If that’s the case for your frame, you’re stuck with 27’s. Personally, if it were me and I couldn’t get it to work with the existing brakes, I’d stick with 27 inch wheels. If you start having to swap brakes out, it starts to get iffy and frankly, I think it’s more hassle than it’s worth.
Is 700c same as 28?
The wheel sizes 28′, 700C and 29er or 29′ all refer to the same rim size: ETRTO 622. The tyres can differ, but the 28′, 700C and 29er are all the exact same rim diameter. The 700 markings will be followed by the width in mm, and the 28 or 29 markings will be followed by the width in inches.
Which is bigger 26 or 700c?
700c vs.26″: Testing Reveals Best Choice for You Santana sells similar numbers of tandems with both wheel sizes and has no ax to grind. Four years ago a respected bike designer confidently predicted the impending demise of 700c tandems. While this was not particularly frightening to Santana (we had designed and promoted 26″ road tandems as far back as 1983), it also didn’t ring true.
- I’ve watched as hundreds of customers tested both sizes before making a decision – was it possible the majority who chose 700c tandems were mistaken? Many people who advocate one size over the other insist on comparing fat 26-inch tires and skinny 700c tires.
- Some make recommendations based on the availability of a particular tread pattern.
Others confuse the issue by comparing 700c tandems designed for pavement with 26″ tandems designed for dirt. Santana’s question was simple: if you were to eliminate the differences in tread width, tread pattern, inflation pressure and frame geometry, is a 26″ wheel superior to a 700c wheel strictly on the basis of its diameter? If yes, why? In an attempt to discover the truth, we prepared some test tandems and asked a number of teams to evaluate them.
- To reduce extraneous perceptions our test bikes used identical tubing and direct-lateral frame style, 26″ and 700c rims produced from the same extrusion, and tires with the same width and tread pattern inflated to the same pressure.
- The honest attempt was to discover the best size – after all, life here at Santana would be a whole lot simpler if we could standardize on 26″ wheels.
But first, some background. The argument over wheel size did not start with tandem riders. Alex Moulton of England produced pro racing bikes with 14-inch sew-up wheels in the late-’60s. In the mid-’70s, Tarn Cycles of Chicago built a series of Campy-equipped full-race singles (and at least one tandem) with 20-inch wheels.
In the early-’80s California’s first production mountain bikes, built by Victor Vincente, were equipped with 20″ wheels. All of these builders argued that bikes with smaller wheels would be superior due to lower weight, stronger wheels, quicker acceleration, and less wind resistance. Critics of these designs claimed bikes with smaller wheels were slower and less stable.
While slower was difficult to prove, some organizers banned small-wheeled bikes from racing (where they might have disproved the “slower” argument) fearing “diminished gyroscopic effect” would inevitably lead to crashes in pack racing events. Fred de Long, Technical Editor of Bicycling, disproved the “gyro” theory in the late ’60s when he assembled a unique bike with side by side front wheels – a normal front wheel plus an identical counter-rotating wheel slightly above and to one side.
- The second wheel (which rotated at the same speed but never touched the ground) offset the gyro effect of the first.
- His finding: a bicycle’s gyro-stability is a myth.
- He postulated (and I agree) that all us cyclists remain upright by continually steering through/across the path of our imminent fall.
- You can quickly prove this to yourself by riding a bike with an over-tightened headset – the results are extremely convincing).
Three years ago there was yet another resurgence of interest in road-racing bikes with smaller-than-700c wheels. For a time you could buy road racing bikes with 26-inch wheels from many serious builders including Serotta and Paramount. While a few large-frame time trial and triathlete bikes are still built around a pair of 26″ wheels, the designers of these bikes are admittedly chasing tiny aerodynamic and weight advantages that will be lost on a tandem (where doubled power reduces the significance of these advantages by 50%).
So what did we learn during Santana’s testing? Our panel of testers uniformly found 700c tandems were more stable at higher speeds. Most testers also believed the tandems with 700c wheels were faster. The difference in “feel” was substantial enough so that an envisioned follow-up “blind” test with carefully shielded-from-view wheels was deemed unnecessary.
Why were 700c tandems clearly more stable? At the time of the testing, none of us had a clue. I later developed a theory, first published three years ago, that the answer was due to the shape of the tires’ contact patch (footprint). If the same mass is supported on tires inflated to the same pr essure, the area of the contact patch must also be the same – this is, after all, the meaning of p.s.i.
- Or “pounds per square inch.” The difference in wheel diameter causes the footprint of the bigger wheel’s tire to be more elongated than the footprint of the tire on the smaller wheel.
- I reasoned a longer footprint would provide greater directional stability at high speeds (as is the case with longer skis, surfboards, and skates).
Until someone comes up with an alternative explanation, this theory not only explains the increase in high speed stability, it also explains why off-road riders might reasonably prefer 26-inch wheels – the rounder footprint provides less steering resistance and easier maneuvering at low speeds.
While my original “footprint” theory explained stability, it didn’t explain the perceived difference in speed. I originally thought it probable our testers were mistaken about a speed advantage for 700c wheels. If they actually rode faster with 700c wheels, I felt certain it was an ephemeral result of enhanced rider confidence.
Put simply, if riders on 700c test tandems felt more confident at higher speeds (because of stability resulting from the shape of the footprint), this confidence might allow a temporary increase in performance. If there was an enduring speed difference, it seemed likely to me the lighter and smaller 26″ wheels would have the advantage.
- Some of you might think the difference in diameter between 26″ and 700c is too small to matter.
- Actually, even though we all know 700c rim is slightly smaller than 27″ rim, a 700c rim is a full 2-1/2 inches larger than 26″ rim.
- Two-and-one-half inches?! How can difference between 26″ and 27″ exceed 2-1/2″?! Answer: a ridiculous tradition dictates that sizes of bicycle wheels – unlike car and motorcycle wheels – indicate the nominal outside diameter of the TIRE, and not the actual diameter of the rim.
While the out side diameter of a traditional 26-inch “balloon” tire is about an inch smaller than the original 27-inch “racing” tire, the rim is nearly 3 inches smaller. The same tradition exists in Europe where there are no fewer than 4 diameters of rims that accept “650” tires (labeled 650-A through 650-D).
- To compare the “real” size of a rim or tire you must know the “bead seat diameter.” Fortunately, this number is found molded into the sidewall of most tires.
- The real size of a 27″ rim is 630mm (about 24.8″), a 700c rim has a bead seat diameter of 622mm, and the “26-inch” rim found on tandems a nd mountain bikes is only 559mm (a mere 22″).
If matching width tires are installed, the outside diameter of a 622 (700c) tire is 63mm (2.5″) larger than the outside diameter of a 559 (26″) tire. I’ve since realized the testers who reported faster speeds on a tandem with 700c wheels were correct – and here’s why: Remember that the area of a tire’s contact patch (or footprint), because it is purely a function of weight and inflation, owes nothing to the diameter or width of a tire.
- It follows that our test tandems with 11% smaller wheels produced footprints that were exactly 11% shorter and, therefore exactly 11% wider.
- Shorter explains the stability difference and wider explains the speed difference.
- Why is wider slower? To apply the extra width against the pavement, the tread and sidewall of the smaller yet equally-wide tire is forced to undergo a great deal of additional contortion – and tread and sidewall squirm are the primary causes of rolling resistance.
Is the difference in rolling resistance enough to produce a significant difference in speed? Because rolling resistance is a much smaller factor than wind resistance, until a few months ago I would have guessed no. Today I’m convinced otherwise – whereas aerodynamic and weight differences are probably only half as significant for tandems (because of doubled power), internal tire friction is probably twice as critical (because of doubled mass).
- Even if 26″ someday proves itself the superior size for road racing singles (it hasn’t yet), the optimal wheel size for a racing tandem will always be larger.
- While determining an exact difference in rolling resistance would be fairly easy, the effect on speed is difficult to ascertain.
- My best current estimate is a 26″ tandem with equivalent rims, tread width, tread pattern and inflation will be 2-4% slower than a 700c tandem.
While this will be a small difference for those who want the flexibility of using their tandem off-road, those interested in ultra-fast pavement rides might expect a cruising speed difference of up to one mile per hour (or a century finishing time difference of 5-10 minutes).
- A couple of final thoughts about ultra-fast road rides on a 26″ tandem.
- To achieve the same gearing as a 700c road tandem with a 54 tooth chainring, a 26″ racing tandem will need a 60 tooth ring – which is incompatible with the curvature of modern front derailleurs.
- And when you want to stop, because braking power is a squared function of effective brake radius, a rim brake on a 26″ tandem is 19% less effective than the same brake on a 700c tandem.
Does this mean 26″ tandems are stupid? Hardly. If you want to conquer the toughest terrain, 700c wheels simply aren’t strong enough. And if we built a 700c frame with sufficient clearance for as-yet nonexistent 2.5″ knobbies (700×63), captains shorter than six feet would have a hard time straddling the top tube.

How do you measure a 700c tire?
Step 2 – Hold the end of the tape measure against the center of the bicycle wheel, and extend the tape in a straight line to the outer edge of the tire. For traditional sizing, double the inches to find the bike tire diameter. To determine the ISO diameter, measure in millimeters from the center of the wheel to only the inner edge of the tire and double the figure.
Is 700c a tire size?
700c – A standard road tire is 700c x 23mm, indicating a tire diameter of approximately 700mm and a width of 23mm. When shopping for road tires, you’ll look for 700c x your preferred width, 23mm being the slimmest option and going up to 36mm.650c: size used on some high-performance road and triathlon bikes, especially those designed for smaller riders.
How do you decode a wheel size?
Which tires and wheels do you need? – You hit a big pothole and hear that distinctive “womp” of a flat tire. You get out to check—the rim is cracked, too. You call a few shops. Your dealership. You get a few price quotes—all outrageous. You want to look online to find better prices, but you have no idea where to start.
- You put in your make and model and are faced with a full page of choices and it all looks like gibberish.
- Ugh! Don’t worry, decoding tire and wheel size is easy once you have a reference for what you’re looking at.
- Tires The size of your tire, assuming your vehicle is stock, is going to be on a sticker on the driver-side door frame.
It will also be in the owner’s manual. The sticker should give you information on the front, rear, and spare tire sizes. More than likely the front and rear tires will be the same; spares are all over the place. All of this info is also molded onto the tire.
” P ” — stands for passenger. As in passenger car. Sometimes it will say “LT” for light truck. Unless you are driving a large commercial truck, it will be “P” or “LT.” ” 245 ” — the width of the tire in millimeters. Why millimeters? Because Michelin invented modern tires and they’re a French company. ” 50 ” — the percentage ratio of sidewall to tire width measured from tread to bead (e.g.50% of 245mm is 122.5mm). The bead is the part that will touch the rim. ” R “—radial. This refers to the construction of the tire. Unless your car is over 40 years old, it has radial tires. ” 17 ” — the diameter of your rim in inches. It will be anywhere from 14 to 22 inches. ” 98 ” — load index. The higher the number, the more load the tire can carry. This number will range from 70 to 126. The heavier your vehicle and intended load, the bigger the number. Some vehicles may have ” XL ” tires, meaning extreme load. ” V ” — the speed rating. “V” is the highest you’d find on a normal car and has a rating of 149mph. Most vehicles will have “S” or “T” or around 112mph or 118mph. Mind you, this is sustained speed. Most tires are going to be going well under these ratings. Look for letters from L to V.
Other markings you will sometimes see are “M+S” or “M/S” for mud and snow, or “AT” for all terrain and “AS” for all season. Most vehicles will come with “AS” tires. If you have run-flat tires on the other wheels, it’s unsafe to replace one with a standard tire.
” 7.5 ” — the width of the rim from bead lip to bead lip—the widest part of the inside of the rim. ” J ” — refers to the bead profile. It’s rare that you’d find something besides “J” on passenger cars. Larger trucks and vans may have “G”, “H”, or “JJ.” Make sure it matches. ” 17 ” — same as the tire: the diameter of the rim. ” H2 ” — refers to the “hump” of the rim. Wheel humps add strength to the rim. This isn’t as important as the other measurements, but it won’t be hard to find the right hump. ” ET44 ” — the offset of the wheel mount from the center of the rim. This can be positive or negative. Negative is closer to the suspension. Positive is further from the suspension of the vehicle. “ET44” means a 44-millimeter positive offset or 44mm off center on the roadside of the rim. “ET” comes from the German word “Einpresstiefe” which means “insertion depth.”
The hole pattern is also important. It’s self-explanatory—four, five, six, or eight holes for most commuter vehicles. The pitch circle diameter (PCD) is the measurement from the center of one bolt hole to the one across from it. This is pretty standard for wheel size and hole pattern.
What is the standard wheel size?
- This is always referred to in inches, and as the name suggests is the diameter of the wheel – not the tyre and wheel together.
- Regular road cars generally have wheels that are between 14 and 21 inches in diameter, with newer, sportier, and more luxurious cars generally having the larger sizes.
- Where you see the wheel size written down such as 7x17in the larger of the two measurements will virtually always be diameter, with the smaller number relating to the width.
Can I put 27.5 tires on 700c?
Choosing an inner tube for a 700c bike tire – Inner tubes are a little easier to pick as they’re a little more forgiving than tires. Tubes are a little like those magician’s modelling balloons. They blow them up, then twist them into various shapes, and out pops a cute model dog for a birthday boy or girl.
The key aspect here is that the width of the balloon varies according to how much air the magician blows into it. Same for inner tubes. This means that any given size of inner tube can be used with a range of tire sizes. Inflated a little more for larger tire widths, inflated a little less for smaller tire widths.
Bear in mind that the overall diameter of the tube won’t change, no matter how much air you blow into it. So, how to choose the correct size of inner tube for your bike wheel? First, find your tire size by looking along the side wall for the tire code.
Let’s say that this is “700c x 38”. You now need a tube that is 700 diameter, with a width range that includes 38. A bike tube that is “700c x 35-40” would therefore be perfect. I like to make things even easier, so all you have to do is take your bike tire code (e.g. “700c x 38”) and look down the table above until you find that code in the left column.
Look across to the right until you see the button that says “View tube”. Click. Buy. Fit. Go out and ride your bike with a grin on your face.
Is a 700c wheel 26 inches?
A Quick Note About Bicycle Wheel Size Terminology and Measurement – Over the years, a number of different bicycle wheel sizes have been developed around the world. In some cases, the size is exactly the same but a different name is used. This is usually done for marketing purposes. A few common bicycle wheel sizes include:
- 700c, 29er, and 28 inch bicycle wheels all have the same rim diameter of ISO 622 mm.700c is the standard wheel size for modern road bikes.29er is basically a marketing term for wide 700c wheels that are made for off-road riding.28 inch is a size that is still used in some parts of the world though it is kind of a vintage rim measurement. Tires and tubes that are labeled 28 inch fit on 700c or 29er rims as long as the rim is a compatible width.700c in inches is around 27.7″.
- 26 inch (ISO 559 mm) wheels are the standard size for older mountain bikes as well as many expedition touring bikes and fat bikes. These wheels measure 559 mm in diameter. These wheels are about 1-2 inches smaller in diameter than a 700c wheel depending on the type of tires that are installed.
- 27 inch (ISO 630 mm) are often found on old road bikes. This size is not the same as 700c or 29er.27 inch wheels are slightly larger than 700c at 630 mm as opposed to 622 mm. This means tires are not cross-compatible with any other wheel sizes.
Tip: While buying tires or rims, it can be helpful to look at the ISO size. This measurement is given in millimeters and was developed by the International Organization for Standardization (ISO). For a visual comparison of the most common bike wheel sizes, check out this cool diagram from rodbikes.com This tire sizing table from sheldonbrown.com can also help.
How are 29 inch wheels measured?
Origins – 29″ and 26″ mountain bike wheels 29er rims have an interior diameter of 622 millimetres (24.5 in) and the average 29″ mountain bike tire is (in ISO notation) 59-622 – corresponding to an outside diameter of about 29.15 inches (740 mm). The typical 26″ MTB tire has a rim diameter of 559 millimetres (22.0 in) and an outside tire diameter of about 26 inches (660 mm).
In the early 1980s, the size of the wheels for the emerging mountain bikes was undecided. So when English off-road cycling pioneer Geoff Apps contacted Gary Fisher and Charlie Kelly with news that he had built a prototype off-road bicycle that used large-diameter 28 × 1¾ ( ISO 47-622), 47mm wide Nokian Hakkapeliitta snow tires from Finland, they were intrigued.
In a letter to the December 2006 issue of Bike Biz magazine, Gary Fisher, speaking about the growing popularity of 29ers, gives his perspective: “We got some tires from Geoff Apps really early on and we said ‘Holy Toledo!'” But the poor supply situation of the larger diameter tires meant the fledgling MTB industry stuck with the smaller wheel size.” The first Geoff Apps-designed 700C wheeled off-road bicycle was made in 1981.
However the bicycle marketed as the Aventura by Apps’ own company, Cleland Cycles Ltd, between 1982 and 1984 used the more readily available Nokian Hakkapeliitta 26 × 2 (ISO 54-584). The 650B size, also known as 27.5″, reappeared in 2007 as a compromise between the 26 inch and 29 inch sizes. The 650B size is called 27.5″.
The name “29er” comes from a bicycle called the Two Niner, which was offered by the Fisher bike company in 2001, according to 1998 Mountain Bike Hall of Fame inductee Don Cook. The US division of Bianchi Bicycles offered a line of 29″ wheeled off-road bikes beginning in 1991 called the Project bikes.
- Their 1992 product catalog raved about the advantages of the larger wheels and showed three different bikes, the Project 3, 5 and 7.
- Likewise, in 1991 Panaracer developed a 700c version of the Smoke Tire for OEM use on the Diamondback Overdrive and Overdrive Comp mountain bikes.
- The original company Klein produced a small quantity of a 29″ wheeled version of their successful “Attitude” MTB racer, and named it the Adept.
It failed to find a market and was discontinued. A key product release, the first true 29″ tire, was produced by an early supporter of the 29″ movement Wilderness Trail Bikes, The company introduced the first true 29″ tire, the Nanoraptor, in 1999. At about the same time, White Brothers produced the first commercially available 29″ suspension forks.
Before then suspension forks used were forks designed for trekking bikes or hybrids. For many years, 29″ frames and bikes were usually only available from small little-known manufactures like Niner Bikes. Surly Bikes introduced their 29″ frameset, the Karate Monkey, in 2002. Gary Fisher Bicycles, a division of Trek Bicycles, became the first of the major manufactures to offer a line of 29″ bikes.
Their lines never sold well until the introduction of single-speed 29″ bike the Rig, in 2004. Today, most bicycle manufacturers in the US market offer at least one 29″ bicycle or frame.
What is the diameter of a 26 inch wheel?
26 inch / ISO 559 mm – 26-inch clincher tires (with inner tubes) were the most common wheel size for new mountain bikes until the early 2010s. This tradition was started initially because the early mountain bike pioneers procured the wheels for their early bikes from American-made bicycles rather than the larger European standards in use.
How many inches is 700c?
A Brief Introduction to 700c Wheels – 700c wheels have been around for many years and are utilised by almost every road and hybrid bike, But obviously, the 700c wheels you’d find on a road bike are drastically different from what you’d expect on a hybrid, so why are they called 700c wheels, you ask? To be honest, this name is almost redundant now since there are so many different 700c wheels and tires available.
- The “700” part refers roughly to the outer diameter of the wheel’s tire.
- Many tire types are available, and a tire’s characteristics, such as tread and anti-flat protection, will impact its diameter.
- The “c” comes from old French Tire sizing and has remained on bike wheels, despite not meaning anything anymore.
The lettering ranged from A to D and referred to the tire’s width, but this is now redundant. The consistent measurement across all 700c tires is their bead seat diameter or BSD. The BSD is the diameter across the tire bead seating points inside the wheel’s rim. You’ll see 622 alongside another number on the wall of all 700c tires, this is known as the ISO (International Organisation for Standardisation) measurement. A road bike’s slim tires might have an ISO measurement of “23 – 622”, the first number refers to the width of the tire when fully inflated and the second is the BSD.
|Bike Type||Common Tire Width Range|
|Road Bike||23 – 28mm||0.9 – 1.1″|
|Cyclocross Bike||28 – 35mm||1.1 – 1.4″|
|Gravel Bike||35 – 45mm||1.4 – 1.8″|
|Hybrid Bike||35 – 45mm||1.4 – 1.8″|
Now that you understand a bit more about 700c wheels and tires, let’s find out about 700c to inches. The most straightforward answer to “700c to Inches” is that 700c equals 27.5 inches. But unfortunately, as you’ll see in the table below, it’s not as straightforward as that.
- If you simply bought a random set of 27.5″ tires, they probably wouldn’t fit your bike as wider tires require more clearance.
- So, for example, if you’re riding a high-end road bike, you won’t be able to use 700 x 47c tires.
- Tires this wide might fit on your wheel, but they’d likely chafe against your frame.
For those who want an accurate tire size conversion, from 700c to inches, you’ll find the diameter of each 700c tire size converted to inches and centimetres in the table below. If you don’t currently have tires on your wheels and need to know what tire size you require, follow this simple guide,

What bike wheel size for my height?
General – Some might assume there’s no need to be too picky about kids’ sizes compared to adults. But on the contrary, you need to ensure your child has utter ease while riding. Most children are not expressive when speaking out about their discomfort.
|Rider’s Height||Inseam (in Inches)||Suggested Bicycle Wheel Size|
|2’10” to 3’4″||86 cm to 101 cm||14″ to 17″||35 cm to 42 cm||12″ Wheels|
|3’1″ to 3’7″||94 cm to 109 cm||16″ to 20″||40 cm to 50 cm||14″ Wheels|
|3’7″ to 4′||109 cm to 122 cm||18″ to 22″||45 cm to 55 cm||16″ Wheels|
|3’9″ to 4’3″||114 cm to 130 cm||20″ to 24″||50 cm to 60 cm||18″ Wheels|
|4’3″ to 4’5″||122 cm to 135 cm||22″ to 25″||55 cm to 63 cm||20″ Wheels|
|4’5″ to 4’9″||135 cm to 145 cm||24″ to 28″||60 cm to 72 cm||24″ Wheels|
|4’9″ onwards||145 cm onwards||28″ onwards||72 cm onwards||26″27.5″ or 700c Wheels (for adult bikes)|
