Title (EN) TIRE
(FR) PNEUMATIQUE
(JA) タイヤ
Abstract:
(EN) This tire (1) has, in a tread part (2), a plurality of land parts (70A)-(70C) sectioned by circumferential direction grooves (50) extending in the tire circumferential direction (L) and width direction grooves (60) extending in the tire width direction (W). The tire (1) is configured so that the length (W2) of the tread part (2) in the tire width direction (W) is 60 to 95% of the length (W1) of the tire (1) in the tire width direction (W). In the tire (1), the sipe density in the land parts (70A) is greater than the sipe density in the land parts (70B)/(70C) that are disposed farther out in the tire width direction (W) than the land parts (70A).
(FR) Le pneumatique (1) de l'invention possède, au niveau d'une partie bande de roulement (2), une pluralité de parties au sol (70A à 70C) divisées par des rainures de direction périphérique (50) se prolongeant dans une direction périphérie de pneumatique (L), et des rainures de direction latérale (60) se prolongeant dans une direction latérale de pneumatique (W). Dans le pneumatique (1), la longueur (W2) de la partie bande de roulement (2) dans la direction latérale de pneumatique (W), est conçue de sorte à correspondre à 60 à 95% de la longueur (W1) du pneumatique dans la direction latérale de pneumatique (W). Enfin, dans le pneumatique (1), la densité de lamelles à l'intérieur des parties au sol (70A), est supérieure à la densité des lamelles à l'intérieur des parties au sol (70B) / (70C) disposées côté externe de la direction latérale de pneumatique (W) par rapport aux parties au sol (70A).
(JA)  タイヤ(1)は、トレッド部(2)において、タイヤ周方向(L)に延びる周方向溝(50)及びタイヤ幅方向(W)に延びる幅方向溝(60)によって区画化された複数の陸部(70A)~(70C)を有する。タイヤ(1)では、タイヤ幅方向(W)におけるトレッド部(2)の長さ(W2)は、タイヤ幅方向(W)におけるタイヤ(1)の長さ(W1)の60~95%となるように構成されている。また、タイヤ(1)では、陸部(70A)内におけるサイプ密度は、陸部(70A)よりもタイヤ幅方向(W)外側に配置されている陸部(70B)/(80C)内におけるサイプ密度よりも大きくなる。
