Title (EN) PNEUMATIC TIRE
(FR) PNEUMATIQUE
(JA) 空気入りタイヤ
Abstract:
(EN) The present invention provides a pneumatic tire which is capable of achieving a good balance among good wet grip performance, elongation at break, and fuel consumption saving performance. The present invention relates to a pneumatic tire which has a tread that is produced using a rubber composition which contains sulfur and a mixture that contains a rosin and a styrene-(meth)acrylic copolymer having a weight average molecular weight of 3,000 or more, while having an acid value of 2-30 mgKOH/g.
(FR) La présente invention concerne un pneumatique qui est en mesure d'atteindre un bon équilibre entre une bonne performance d'adhérence sur sol mouillé, un bon allongement à la rupture et une bonne performance d'économie de consommation de carburant. La présente invention concerne un pneumatique qui présente une bande de roulement qui est produite à l'aide d'une composition de caoutchouc qui contient du soufre et un mélange qui contient une colophane et un copolymère styrène/(méth)acrylique présentant un poids moléculaire moyen en poids de 3000 ou plus, tout en présentant une valeur d'acide de 2 à 30 mg de KOH/g.
(JA) 本発明は、良好なウェットグリップ性能、破断伸び及び低燃費性能を両立できる空気入りタイヤを提供する。 本発明は、ロジン類及び重量平均分子量3000以上のスチレン-(メタ)アクリル共重合体を含み、酸価2~30mgKOH/gである混合物と、硫黄とを含有するゴム組成物を用いて作製したトレッドを有する空気入りタイヤに関する。
