AIRLESS SUPPORT

Tannus Airless Tire Sizing

Your inner rim width determines which tires will fit your bicycle as well as which locking pins you will need for a proper fit.

How to measure
• Remove your old tire
• Use a ruler or caliper tool to measure - see image
• Once you have the correct measurement, you can find the correct tire
