Air-to-air radial tires for heavy-duty applications that improve belt durability

摘要

SUMMARY OF THE INVENTION The present invention is directed to providing an air-inlet radial tire for a load which can reduce the shear stress generated between belt layers to improve the durability of the belt.;Conventionally, a belt edge stripper, which is a triangular rubber extruded product for absorbing and buffering shear stress, is installed between both ends of the second belt and the third belt. However, since the belt edge stripper is being deformed due to stress, The present invention has a drawback in that the edge portion between the second and third belts is more firmly coupled with the edge portion of the belt so as to prevent the occurrence of separation at the belt portion. The present invention relates to an air-inlet radial tire for heavy load, which is capable of suppressing occurrence of separation at both side ends of two belts and a third belt, And a reinforcing belt 6 provided at an outer side of the belt edge stiffener 5 provided between both ends of the belt edge stiffener 5 at an angle parallel to the second belt 2.
