Title (EN) STUDDED TIRE AND TIRE RUBBER COMPOSITION
(FR) PNEU CLOUTÉ ET COMPOSITION DE CAOUTCHOUC POUR PNEU
(JA) スタッドタイヤおよびタイヤ用ゴム組成物
Abstract:
(EN) Provided is a studded tire in which, by increasing the grip performance of stud pins, the performance on ice/snow is enhanced so as to be equal to or greater than a level achieved by the related art. Provided is a studded tire in which studded pins are provided on a tread surface of a tread section, wherein the studded tire is characterized in that: the tread section is formed of a cap tread and an under tread; and, when it is assumed that, for the cap tread and the under tread, Hc and Hu are rubber hardnesses at 20ºC, Sc and Su are tensile stresses (MPa) at 23ºC when being stretched by 300%, relational expressions Hc ≤ 60...(1), Hu - Hc ≥ 8...(2), Sc ≥ 5.5...(3), and Su/Sc ≥ 2.0...(4) are satisfied.
(FR) L'invention concerne un pneu clouté dans lequel, en augmentant la performance d'adhérence de broches de clous, la performance sur glace/neige est améliorée de manière à être supérieure ou égale à un niveau obtenu par l'état de la technique associé. L'invention concerne un pneu clouté dans lequel des broches cloutées sont disposées sur une surface de bande de roulement d'une section de bande de roulement, le pneu clouté étant caractérisé en ce que : la section de bande de roulement est formée d'une bande de roulement de chape et d'une bande de roulement inférieure ; et, lorsqu'il est supposé que, pour la bande de roulement de chape et la bande de roulement inférieure, Hc et Hu sont des duretés de caoutchouc à 20 °C, Sc et Su sont des contraintes de traction (MPa) à 23 °C lorsqu'elles sont étirées de 300 %, les expressions relationnelles Hc ≤ 60... (1), Hu-Hc ≥ 8... (2), Sc ≥ 5,5... (3) et Su/Sc ≥ 2,0... (4) sont satisfaites.
(JA) スタッドピンの保持能力を高くして、氷雪上性能を従来レベル以上に向上するようにしたスタッドタイヤを提供する。トレッド部の踏面にスタッドピンを植設したスタッドタイヤであって、前記トレッド部がキャップトレッドおよびアンダートレッドからなり、前記キャップトレッドおよびアンダートレッドの20℃におけるゴム硬度をHcおよびHu、23℃における300%伸長時の引張応力(MPa)をScおよびSuとするとき、以下の関係式;Hc≦60…(1)、Hu-Hc≧8…(2)、Sc≧5.5…(3)、Su/Sc≧2.0…(4)を満たすことを特徴とするスタッドタイヤ。
