Michelin® Airstop® tubes are made with 100% butyl rubber, preferred for its ability to maintain air pressure over long periods of time
Butyl is also highly resistant to wear and friction, and easily repaired
Unlike inexpensive tubes, which are made from straight sections of rubber tube formed into a circle, Michelin Airstop tubes are manufactured and cured in a circular mold
This method reduces tension on the tube when inflated, and diminishes the likelihood of pinch flats
Michelin Airstop tubes are available in a wide array of sizes
Each size is designed for only a few specific applications, so that tube and tire match perfectly without placing undue stress on the tube
Reinforced tubes available for off-road applications, for enhanced protection against punctures
