Abstract
(EN) In order to make it possible to maintain a low dynamic storage modulus at low temperature in tread rubber, which is the portion of a tire in contact with a road surface, i.e., to maintain flexibility of the rubber, with no change in the dynamic storage modulus at normal temperature of the tread rubber, the present invention provides a tire in which foamed rubber is provided to the surface of tread rubber, the foamed rubber being constituted from a rubber composition in which a phenol resin is blended.
(FR) Afin de permettre de conserver un faible module de stockage dynamique à basse température dans un caoutchouc de bande de roulement, qui est la partie d’un pneumatique se trouvant en contact avec une surface de route, c’est-à-dire, pour maintenir la flexibilité du caoutchouc, sans changement dans le module de stockage dynamique à la température normale du caoutchouc de bande de roulement, la présente invention concerne un pneumatique dans lequel le caoutchouc expansé est disposé au niveau de la surface du caoutchouc de bande de roulement, le caoutchouc expansé étant constitué d’une composition de caoutchouc dans laquelle une résine de phénol est mélangée.
(JA) 路面に接する部分であるトレッドゴムの常温の動的貯蔵弾性率は変えず、低温での動的貯蔵弾性率を低く、すなわちゴムが柔らかいまま維持することができることを目的として、フェノール系樹脂が配合されたゴム組成物により構成される発泡ゴムをトレッドゴムの表面に備えるタイヤを提供する。
