Bike Tire Sizes Chart

Last updated: 2022-08-27

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.

Bike tires 28 inch

28-inch tires can be found on most adult bicycles. They are usually mounted on the road bike, trekking bike, city bike and e-bike.

28-inch bicycle tires usually have an inner diameter of 622 mm, occasionally also 635 mm or 642 mm. From 50 mm tire width is also known as 29-inch bike tires, so these tires in the following size table have the inch sizes 28" and 29". Due to the different tire inner diameters, it is essential to pay attention to the standardized ETRTO size designation when buying a tire.

Bike tires 27.5 inch

27.5-inch bike tires are available in tire widths up to 75 mm and are often mounted on mountain bikes for children. Unlike 29-inch MTB tires, the MTB tires in 27.5 inches accelerate faster because they have a smaller diameter.

The tire size 27.5" is a marketing term for particularly thick 26-inch tires. Their tire inner diameter of a 27.5" has 584 mm which is smaller than the tire inner diameter of 27-inch tires.
