Bike Tire Sizes Chart

Last updated: 2024-10-19

In the bike tire sizing chart below you can find common bike tire sizes, each listed in a table with the respective tire widths. So it is easy to compare the different sizes in inches, ETRTO and the French designation.

The ETRTO size is standardized and precise, so it is a good starting point when buying a new bicycle tire. The inch size and French size, on the other hand, are quite inaccurate and have sometimes been misstated in the past for marketing purposes, for example, to offer an even lighter tire in “the same” size as the competitors. This explains why in the following tables the same size specifications sometimes “fit” several ETRTO sizes.

Bike tires 29 inch

29-inch bicycle tires are particularly wide tires from 50 mm tire width. Most often they are mounted on the mountain bike (MTB) and are called 29-inch MTB tires.

The tire size 29" is actually a marketing term for particularly thick 28-inch tires. Both inch sizes, 29" and 28", have the same tire inner diameter of 622 mm. So theoretically they can be mounted on the same rims, but the tire width should also fit the rim width.

Tire inner diameter	Tire width	ETRTO	Inch size
622 mm	50 mm	50-622	29 x 2.00 28 x 2.00
622 mm	54 mm	54-622	29 x 2.10 28 x 2.10
622 mm	55 mm	55-622	29 x 2.15 28 x 2.15
