Title (EN) PNEUMATIC TIRE
(FR) BANDAGE PNEUMATIQUE
(JA) 空気入りタイヤ
Abstract:
(EN) A plurality of blocks 7 are formed on a tread surface 1 of a pneumatic tire, and inclined grooves 43 are formed in the blocks. The inclined grooves include connecting parts 43a connect to circumferential main grooves, wide parts 43b that are connected to the connecting parts, and narrow parts 43c that are connected to the wide parts. The wide parts and the narrow parts have smaller angles of inclination relative to the tire circumferential direction than the connecting parts, sipes 52a that open at one end into the connecting parts and open at the other end into the circumferential-direction main grooves are formed in the blocks, and the sipes have crooked parts.
(FR) Une pluralité de blocs (7) est formée sur une surface de bande de roulement (1) d'un bandage pneumatique, et des rainures inclinées (43) sont formées dans les blocs. Les rainures inclinées comprennent des parties de raccordement (43a) se raccordant à des rainures principales circonférentielles, des parties larges (43b) qui sont raccordées aux parties de raccordement et des parties étroites (43c) qui sont raccordées aux parties larges. Les parties larges et les parties étroites présentent des angles d'inclinaison inférieurs à ceux des parties de raccordement par rapport à la direction circonférentielle du pneu, des lamelles (52a) qui s'ouvrent au niveau d'une extrémité dans les parties de raccordement et s'ouvrent au niveau de l'autre extrémité dans les rainures principales de direction circonférentielle sont formées dans les blocs, et les lamelles présentent des parties tordues.
(JA) 空気入りタイヤは、トレッド踏面1に複数のブロック7が形成されており、ブロックには傾斜溝43が形成されており、傾斜溝は、周方向主溝に連結する連結部43aと、連結部に連結する広幅部43bと、広幅部に連結する狭幅部43cとを含み、広幅部及び狭幅部は、連結部よりもタイヤ周方向に対する傾斜角が小さく、ブロックには、一端が連結部に開口し、他端が周方向主溝に開口するサイプ52aが形成されており、サイプは屈曲部を有している。
