What are Bicycle Tyre Sizes?

Bicycle tyre sizes are denoted by two numbers, which represent the width of the tyre in millimeters (mm), and the inner diameter of the wheel in inches. For example, a common road bike tyre size is 700x23c, which means the tyre is 23 mm wide and will fit on a 700c wheel. The second number (700c in this case) is always expressed in millimeters.

Bicycle tyre sizes can be a bit confusing, but once you know the basics, it’s not so bad. Here’s a quick rundown of the most common sizes you’ll see. The first number is the diameter of the tyre in inches.

The second number is the width of the tyre in millimeters. So, for example, a 26 x 2.1 tyre is 26 inches in diameter and 2.1 inches wide. Common mountain bike tyres sizes are 26 x 1.95, 27.5 x 2.2, and 29 x 2.25 (these are all measured in inches).

For road bikes, you’ll see 23, 25, and 28mm tyres which are all pretty similar width-wise; it’s mostly the diameter that differs between road bike tyres and mountain bike tyres. There are some other less common bicycle tyre sizes out there too, but these are the most popular ones that you’re likely to see. Now you know!

Is 26 Inch Bike Tire the Same As the 700C?

A 26-inch bike tire is not the same as a 700C. The difference between the two is that a 26-inch bike tire is sized based on the wheel diameter, while a 700C is sized based on the ISO standard. In addition, a 26-inch bike tire will have a narrower width than a 700C.

What Do Bicycle Tire Sizes Mean?

Bicycle tire sizes are actually quite simple to understand once you know what all the numbers and letters stand for. Here is a breakdown of what each element in a typical bicycle tire size designation means: The first number is the diameter of the tire in inches.

The second number is the width of the tire in millimeters. The letter after the width is the code for the type of bead seat used on the rim. “R” stands for “radial,” which is the most common type.

“B” stands for “bias belted,” and “D” stands for “diagonal.” Finally, there may be a dash followed by another number, which is simply an aspect ratio; it expresses how tall the sidewall is as a percentage of the width. For example, if this number were 50, that would mean that the sidewall was half as wide as the tire was wide; if it were 30, that would mean that the sidewall was 30% as wide as the tire was wide, and so on.

Now that you know what all those numbers and letters mean, you can easily read any bicycle tire size designation. For instance, a common size for mountain bike tires is 26 x 2.1-inch tires; this means that they have a diameter of 26 inches and are 2.1 inches wide with radial bead seats. Another common size is 700C x 23mm tires; these are road bike tires that have a 700C (approximately 27-inch) diameter and are 23mm wide with radial bead seats. Hopefully, this article has helped clear up any confusion about reading bicycle tire sizes!

What is the difference between a 700 And a 700C Bicycle Tire?

There are a few key differences between 700 and 700C bicycle tires. The most notable difference is in the diameter of the tire. A 700C tire is about an inch larger in diameter than a 700 tire.

This may not seem like much, but it can make a big difference in how your bike handles on the road. Another difference is that 700 tires are typically narrower than 700C tires. This again can affect the handling, as well as make it easier to get a puncture if you hit a pothole or sharp object.

Finally,700 tires are usually made from thinner material than 700C tires. This makes them lighter weight, but also means they’re more susceptible to punctures and flats. So, if you’re looking for a tire that’s bigger and thicker, go with a 700C.

What Does 700C Mean in Tires?

When shopping for tires, you may have seen the term 700C and wondered what it meant. 700C refers to the tire size, which is the diameter of the tire. The C in 700C stands for centimeters.

A 700C tire is about 27.5 inches in diameter. This is a common size for road bikes and some touring bikes.

Bicycle Tire Sizes Explained

Bicycle tire sizes can be a bit confusing, but this article will help clear things up. There are two main types of bicycle tires: road bike tires and mountain bike tires. Road bike tires are usually thinner and have less tread than mountain bike tires.

This is because road bikes are designed for speed and efficiency, while mountain bikes are designed for stability and traction. The most common road bike tire size is 700c. This refers to the diameter of the tire in millimeters.

The width of the tire varies, but most road bike tires are 23mm or 25mm wide. Mountain bike tires tend to be wider than road bike tires, with widths ranging from 2.3 inches to 3 inches. The most common mountain bike tire size is 26 inches, which refers to the diameter of the tire in inches.

There are a few other less common bicycle tire sizes, but these are the two you’re most likely to see. Now that you know what all those numbers mean, you can start shopping for new tires!

Road Bike Tyre Sizes 700C

Road bike tyre sizes can be a bit confusing, but this quick guide will help you choose the right tyres for your bike. The most common road bike tyre size is 700C. These tyres are designed for use on paved roads and provide good traction and durability.

If you’re planning on doing any off-road riding, you’ll need to choose a different tyre size. There are two main types of 700C tyres: clincher and tubeless. Clincher tyres have an inner tube that holds air, while tubeless tyres don’t require an inner tube.

Tubeless tyres are becoming increasingly popular as they offer a smoother ride and fewer flats. When choosing 700C tyres, you’ll also need to decide on the width. Tyre widths range from 23mm to 32mm and beyond.

Wider tyres provide more comfort and grip, but they can also make pedaling harder work. Narrower tyres are lighter and faster, but they won’t absorb bumps as well. Most road bikes come equipped with either 25mm or 28mm tyres, but if you’re unsure which width is best for you then it’s worth talking to a knowledgeable cycle shop assistant before making your final decision.

Bike Tire Size for Height

Bike Tire Size for Height When it comes to finding the right bike tire size for your height, there are a few things to keep in mind. First, you’ll want to make sure that the tires you select are appropriate for the type of bike you’re riding.

For example, if you’re riding a mountain bike, you’ll want to choose tires that are designed for off-road use. Conversely, if you’re riding a road bike, you’ll want to choose tires that are designed for paved surfaces. Second, you’ll need to take your own height into account.

If you’re on the taller side, you may need to purchase larger bike tires in order to accommodate your height. Conversely, if you’re shorter than average, you may be able to get away with smaller bike tires. Ultimately, it’s important to experiment until you find a tire size that feels comfortable for YOU.

Finally, keep in mind that tire width also plays a role in how comfortable your ride will be. Generally speaking, wider tires provide more stability and traction than narrower ones – but they can also be more difficult to maneuver (especially on tight turns). So, if possible, it’s always best to test out different tire widths before making a final decision.


Bicycle tyre sizes can be confusing to many riders. The international standard for bicycle tyres is ISO 5775 and it defines both the bead seat diameter and the width of the tyre. However, many bike manufacturers print their own codes on the side of tyres which can be very different from ISO standards.
