(JA) タイヤ
Abstract
(EN)
This tire is configured from a rubber composition which contains, per 100 parts by mass of the rubber component, 0.20 parts by mass of a branched alkane with 40-70 carbons and which has a 30°C tanδ of less than or equal to 0.16. The tire has a cap tread provided with sipes which have a three-dimensional shape, or sipes in which the part with the maximum cross-sectional area is inside the tread surface and the maximum cross-sectional area of the sipes is at least 1.1 times the minimum cross-sectional area.
(FR)
La présente invention concerne un pneumatique qui est conçu à partir d'une composition de caoutchouc qui contient, pour 100 parties en masse du composant de caoutchouc, 0,20 parties en masse d'un alcane ramifié avec 40 à 70 atomes de carbone et qui a une tanδ de 30 °C inférieure ou égale à 0,16. Le pneumatique a une bande de roulement de capuchon pourvue de lamelles qui ont une forme tridimensionnelle, ou des lamelles dans lesquelles la partie ayant la surface de section transversale maximale est à l'intérieur de la surface de bande de roulement et la surface de section transversale maximale des lamelles est d'au moins 1,1 fois la zone de section transversale minimale.
(JA)
ゴム成分100質量部に対し、炭素数40~70の分岐アルカンを0.20質量部以上含み、30℃tanδが0.16以下であるゴム組成物により構成され、3次元形状を有するサイプ、またはサイプにおいてトレッド表面よりも内側に最大断面積となる部分があり、サイプの最大断面積が最小断面積の1.1倍以上であるサイプを備えるキャップトレッドを有するタイヤ。
