Bike tire dimensions: What does 700x40c mean? Tire dimensions are described using two numbers— for example 700 x 40c. The first number refers to the diameter and the second number is the tire width. On a 700x40c tire, the first number indicates that the **outside diameter is approximately 700 millimeters**.

## What does 700x32c mean?

What does 700x32c really mean? 700x32c is basically the size of your tire as measured using the old ‘French system’. If we look at this in details we can see that 700 is the approximate (or nominal) diameter using millimeters of the bike tire.

## What does 700×25 28c mean?

**“700” is the overall diameter of the bike tire, measured in millimeters.** **“28” is the width of the tire, again in millimeters and “c” refers to the width code of the tire** (like you’d see when you look at your bike either from behind or in front).

## What does 700x35c mean?

700x35c is **the dimension of your bicycle tire, as measured using the ‘French system’**. Breaking this down, 700 is the nominal diameter of the bike tire in millimeters. The next number, 35, is the nominal width of the tire (again, this is measured in millimeters).

## What does the C stand for in wheel size?

The C-Type tire, on the other hand, is specifically meant as a **commercial-rated tire**, with a higher load rating for a given size than many LT tires. These C-Type tires will show the letter “C” immediately after the wheel diameter in the tire code. Example: 225/75R16C.

## What does the C mean on a bike tire?

Typical road bike tire: 700 x 32c indicates a tire that has an outer diameter of 700mm and a width of 32mm. (Note that the “c” **does not stand for centimeters**; it’s a holdover from an old French system that designated tire sizes using the letters a, b and c.)

## Is 700 and 700C the same?

The 700C marking you see on most road tires is a nod to that old French tire sizing convention. 700 refers to the approximate diameter in millimeters of the tire. Though rarely seen, there used to be 700A, 700B and 700C tires. **Technically, all share the same outside diameter**.

## What is the difference between 700x25c and 700x35c?

## Is a 28 inch wheel the same as 700c?

In fact, **28″, 700C and 29″ wheels all refer to the same rim size**. These different sizes are used as marketing terms. 700 and 700A wheels are uncommon now, but 700B wheels have an ISO of 635mm and are still used worldwide by several gravel and other off-road inclined bikes.

## Which is bigger 26 or 700c?

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**.

## Do bigger bikes go faster?

**Push bikes with larger wheels can go faster than the ones with smaller wheels** because the radius of the wheel is larger they are also more stable at higher speeds.

## Can you put a 26 wheel on 700c bike?

Wheel Overlap on Small Frames

This is one reason why Surly only offer 700c wheels on their touring bike frames over 56cm. If you are on the smaller size, it makes sense to use 26″ wheels that reduce toe-overlap and the stand-over height of your bike. **Toe overlap can be reduced by using a 26inch wheel over a 700c**.

## Will a 700c tire fit a 26 inch rim?

It’s possible to find 26-inch tires that will fit on 700c rims, but **a 700c tire will not fit on a 26-inch rim without stretching the sidewalls of the tire just enough to make it fit**, especially if you use a tire with especially thick sidewalls.

## What is the difference between 700c and 26 inch wheels?

A 26 inch, or a 650c wheel is **about 1 inch smaller (about 2 inches smaller with road slicks) in diameter than a 700c**. On smaller bikes, that 2 inches is a big help in building the perfect size without sacrificing performance.
