Puncture resistant mute explosion-proof cushion for tyre and wheel thereof

Abstract

A puncture resistant mute explosion-proof cushion for a tyre and a wheel thereof are provided. The explosion-proof cushion is annular, received in the tyre and made of composite nano vinyl acetate copolymer. The explosion-proof cushion includes an inner ring and an outer ring wrapped on the inner ring; when the explosion-proof cushion is installed in the tyre, the outer ring is attached to a top surface and a side surface of an inner wall of the tyre, and a height from the inner ring to the outer ring along a radial direction of the explosion-proof cushion is less than a height of the side surface of the inner wall of the tyre. The explosion-proof cushion of the present disclosure can improve comfort during ordinary driving of the tyre, and simultaneously can protect an integral structure of the wheel when the tyre runs under a condition of a tyre burst.
