Title (EN) PNEUMATIC TIRE
(FR) BANDAGE PNEUMATIQUE
(JA) 空気入りタイヤ
Abstract:
(EN) Provided is a pneumatic tire that includes, in specified proportions, natural rubber, terminally modified styrene-butadiene rubber, silica, and a thermoplastic resin, the pneumatic tire being such that a rubber composition having high dynamic strain dependency of the storage elastic modulus is used in a tread section, the pneumatic tire has a rubber reinforcing layer having a gauge thickness in a specified range, and wet grip properties are balanced while run-flat durability is improved.
(FR) L'invention concerne un bandage pneumatique qui comprend, dans des proportions spécifiées, du caoutchouc naturel, du caoutchouc styrène-butadiène à terminaison modifiée, de la silice et une résine thermoplastique, le bandage pneumatique étant tel qu'une composition de caoutchouc ayant une dépendance de contrainte dynamique élevée du module d'élasticité de stockage est utilisée dans une section bande de roulement. Le bandage pneumatique comporte une couche de renforcement en caoutchouc ayant une épaisseur de référence dans une plage spécifiée et des propriétés d'adhérence sur sol mouillé sont équilibrées pendant que la durabilité de roulage à plat est améliorée.
(JA) 天然ゴム、末端変性スチレン-ブタジエンゴム、シリカ、熱可塑性樹脂を特定配合で含み、貯蔵弾性率の動歪依存性が大きいゴム組成物をトレッド部に用い、特定範囲のゲージ厚のゴム補強層を有する、ランフラット耐久性を向上させつつ、ウェットグリップ性を両立させた空気入りタイヤを提供する。
