Airless Tyres Size Guide

Tannus airless tyres are compatible with any clincher rim. Most bicycle rims nowadays are clincher. This is the metal beading on the inside of your rim that holds the tire onto the rim.

We separate our airless tyres by rim width. We try to make our tyre sizes in lines with the industry standard, so if you currently use a 700 x 25C for example, you would generally speaking run a 700 x 25C Tannus airless tyre. Rim manufacturers vary and current trends might mean that in fact a regular 700 x 25C tyre is in fact a Tannus 700 x 28C. Don’t worry, we have made it super easy for you to find your tire size below.

You'll find your tyre size on the sidewall of the tyre (see the diagram below) and the full spec of each tyre size in the table. If you have any questions we are here to help. Simply use the Live Chat feature in the bottom corner of any web page to speak to our team or click here to email us.
