Title (EN) PNEUMATIC TIRE
(FR) PNEUMATIQUE
(JA) 空気入りタイヤ
Abstract:
(EN) Provided is a pneumatic tire that achieves both wet performance when in contact with low-temperature road surfaces and low rolling resistance, said pneumatic tire characterized by comprising: a tread obtained from a rubber composition containing specific amounts of a natural rubber and a modified styrene-butadiene copolymer rubber, as well as a reinforcing filler and a thermoplastic resin; and a rubber chafer obtained from a rubber composition containing carbon black that has a large particle size and exhibits specific physical properties.
(FR) L'invention concerne un pneumatique qui obtient à la fois une performance sur sol humide lorsqu'il est en contact avec des surfaces de route à basse température et une faible résistance au roulement, ledit pneumatique étant caractérisé en ce qu'il comprend : une bande de roulement obtenue à partir d'une composition de caoutchouc contenant des quantités spécifiques d'un caoutchouc naturel et d'un caoutchouc copolymère de styrène-butadiène modifié, ainsi qu'une charge de renforcement et une résine thermoplastique; et une bandelette talon en caoutchouc obtenue à partir d'une composition de caoutchouc contenant du noir de carbone qui a une grande taille de particule et présente des propriétés physiques spécifiques.
(JA) 特定量の天然ゴムと変性スチレン-ブタジエン共重合体ゴム、補強性充填剤と、熱可塑性樹脂を含むゴム組成物を用いたトレッド部と、特定物性で示される大粒径カーボンブラックを含む、ゴム組成物を用いたゴムチェーファ部を具えることを特徴とする、低転がり抵抗性と、低温路面接地時におけるウェット性能を両立した空気入りタイヤを提供する。
