PNEUMATIC TIRE

摘要

A pneumatic tire has a toroidal carcass layer, a belt layer, and a first fiber reinforcing layer which is arranged so as to cover both end portions of the belt layer, wherein a reinforcing rubber layer is arranged between the first fiber reinforcing layer and the belt layer at a shoulder portion at one side at which the shoulder portion is positioned at an inner side of the vehicle at the time of installing the tire, and a second fiber reinforcing layer is arranged in adjacent to the outer side or the inner side of the first fiber reinforcing layer at a shoulder portion at the other side at which the shoulder portion is positioned at the outer side of the vehicle, and wherein a peeling strength of the reinforcing rubber layer is higher than a peeling strength of the belt layer and the first fiber reinforcing layer.
