Abstract
Official abstract text for this publication.
A pneumatic tire tread capable of mitigating air column resonance and maintaining drainage performance while ensuring that the flexible fences are abraded to a similar extent to the tread portion is formed from a rubber composition, and has a tread portion in which at least one primary groove is formed and multiple flexible fences is formed in the primary groove; the flexible fences are formed from at least a rubber composition for fences that is different from the rubber composition for the tread portion; the rubber composition for fences of the flexible fences has an abrasion index that is more than or equal to twice the abrasion index of the rubber composition of the tread portion; and the rubber composition for fences comprises a filler composition that is based on (a) a diene elastomer, (b) a reinforcing filler which is less than 50 phr; (c) a plasticizing system, and (d) a vulcanizing system.
