Foam Inserts for Off-Road Tires · 16″ / 18″ / 19″ / 21″

Foam Insert · 15 Sizes · Made by Qingdao Zhengya Rubber
A mousse is a foam ring that goes inside an off-road tire instead of an inner tube. With no air inside, a puncture can't leave the rider with a flat. The 15 sizes are listed below. We don't publish pressure or lifetime figures: both depend on the tire, the rim, the riding and how the mousse is fitted and lubricated.
