Note: Traditional tire size designations are confusing, and can lead to considerable trouble. For instance, a 26 x 1.75" tire will not fit a 26 x 1 3/4" rim!This page mainly uses the modern I.S.O. sizing system, though it also lists the traditional national based systems.
For a thorough explanation of tire sizing systems,
see my Tire Sizing Article. It's best if you can read the tire size from your old tire, but if you don't have an old tire, or the marking is illegible, you can
Measure the Rim...here's how! For an overview of tire information to help you choose, and to get the best results from your tires:
see my General Article on Tires.
