Title
(EN) PNEUMATIC TIRE TREAD
(FR) BANDE DE ROULEMENT DE PNEUMATIQUE
(JA) 空気入りタイヤ用トレッド
Abstract
(EN)
Provided is a pneumatic tire tread whereby it is possible to reduce air column resonance and maintain drainage performance, while also ensuring that flexible fences abrade at the same rate as the tread section. A pneumatic tire tread (1) according to the present invention is formed from a rubber composition and has a tread section (2) in which at least one main groove is formed, and a plurality of flexible fences (4) formed in the main groove. The flexible fences are formed from a rubber composition for fences which differs at least from the rubber composition of the tread, and the rubber composition for fences has an abrasion resistance index that is at least twice the abrasion resistance index of the rubber composition for the tread section. The rubber composition for fences includes a filler composition that has, as a base, (a) a diene elastomer, (b) less than 50 phr of a reinforcing filler, (c) a plasticizing system, and (d) a vulcanizing system.

L'invention porte sur une bande de roulement de pneumatique au moyen de laquelle il est possible de réduire la résonance de la colonne d'air et de maintenir la performance de drainage, tout en assurant en même temps que des barrières flexibles s'usent à la même cadence que la section bande de roulement. Une bande de roulement de pneumatique (1) selon la présente invention est formée d'une composition de caoutchouc et possède une section bande de roulement (2) dans laquelle au moins une rainure principale est formée, et une pluralité de barrières flexibles (4) formées dans la rainure principale. Les barrières flexibles sont formées d'une composition de caoutchouc pour barrières, qui diffère au moins de la composition de caoutchouc de la bande de roulement, et la composition de caoutchouc pour barrières a un indice de résistance à l'abrasion qui est au moins deux fois l'indice de résistance à l'abrasion de la composition de caoutchouc utilisée pour la section bande de roulement. La composition de caoutchouc pour barrières comprend une composition de charge qui a, comme base, (a) un élastomère diène, (b) moins de 50 phr d'une charge renforçante, (c) un système plastifiant, et (d) un système vulcanisant.
