【Quality Materials】The inner tubes are made of Isobutylene Isoprene Rubber, which provides better air tightness, elastic damping, and aging resistance compared to natural rubber. The inflatable inner tubes feature TR87 bent valve stems and are designed with high puncture resistance, extra secure welded seams, and are ISO/TS16949 certified.

【Package Contents】Each package includes 1 x 10-inch inner tube. Please note that it is crucial to check the tire inflation pressure regularly, at least twice a month or before long-distance driving, to avoid unstable driving or tire damage due to incorrect pressure.

【Service Guarantee】Before installation, please check if the inner tubes are completely sealed by submerging them in water. If any bubbles are present, the tubes are already damaged. If you encounter this situation, please contact us, and we will promptly replace the product with a new one.
