Abstract

PURPOSE: To enhance anti-cut and anti-burst characteristics without reducing the separation resistant property by providing a narrow reinforcement ply consisting of cord of the same material as the ply, between plies of the carcass body.
CONSTITUTION: Between plies 2 of the carcass body, narrow reinforcement plies 3 consisting of cord with the same material as the ply 2 shall be provided, and the end of the bunch 3a of these reinforcement plies 3 shall be arranged in the intermediate zone situated between the shoulder and the tire carcass's maximum point in sectional width while the end of the bunch 3b in the zone between the shoulder and the crown center. By this construction, the carcass can be strengthened according to frequence and magnitude of any outer force or damage thereof which may be applied to the carcass, so that any excessive increase of the number of plies at the side part can be suppressed, which can lead to setting the spring constant of the tire at a resonable value, decreasing the external force to be applied to the crown part and enhancing the anti-cut and anti-burst characteristics.
