Rubber tire with puncture preventive layer

Abstract

The present utility model discloses a pneumatic rubber tire comprising a body and an internal coating layer tightly attached to the inner wall of the tire body, said internal coating layer having elastic property adapted to prevent deflation of the pneumatic rubber tire from puncture from sharp objects. The internal coating layer is made of synthetic polymer gel and the attachment thereof with the inner wall of the tire body is facilitated by a reversible adhesive. The provision of the flexible and elastic internal coating layer acts as a self-sealing layer for small punctures such as punctures from nails.
