Michelin Tube 70/100 x 19 Junior MX

• 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
