要約
(EN) In this tire, multiple outside notches separated in the tire circumferential direction are formed on an inside (in the tire width direction) wall of outside land parts which are each disposed outside (in the tire width direction) two central circumferential grooves respectively, the inside wall being exposed in the corresponding central circumferential groove. Each of the multiple outside notches corresponds to a block land part, extend outward in the tire width direction, and terminate in the middle of the corresponding outside land part. At least a part of the inside (in the tire width direction) opening of each of the outside notches is positioned between the maximum position A where the distance of the corresponding block land part in the tire width direction is the greatest, and the midpoint B between two adjacent apexes on the outside (in the tire width direction) wall of the block land part.
(FR) La présente invention concerne un pneu qui comprend plusieurs encoches extérieures séparées dans la direction circonférentielle du pneu formées sur une paroi intérieure (dans le sens de la largeur du pneu) de parties d'appui extérieures qui sont chacune disposées à l'extérieur (dans le sens de la largeur du pneu) de deux rainures circonférentielles centrales respectivement, la paroi intérieure étant visible dans la rainure circonférentielle centrale correspondante. Chacune des multiples encoches extérieures correspond à une partie d'appui de bloc, s'étend vers l'extérieur dans le sens de la largeur du pneu, et se termine au milieu de la partie d'appui extérieure correspondante. Au moins une partie de l'intérieur (dans le sens de la largeur du pneu) ouverte de chacune des encoches extérieures est positionnée entre la position maximale A où la distance de la partie d'appui de bloc correspondante dans le sens de la largeur du pneu est la plus grande, et le point du milieu B entre deux sommets adjacents sur la paroi extérieure (dans le sens de la largeur du pneu) de la partie d'appui de bloc.
(JA) タイヤは、2本の中央周溝よりタイヤ幅方向外側にそれぞれ設けられた外側陸部の中央周溝に露出するタイヤ幅方向の内側側壁に、ブロック陸部にそれぞれ対応し、タイヤ幅方向の外側に向かって延びるとともに、該外側陸部の途中で終了する外側切り欠きがタイヤ周方向に離して複数形成され、さらに、該外側切り欠きのタイヤ幅方向内側開口の少なくとも一部が、対応するブロック陸部のタイヤ幅方向距離が最大である最大位置Aと、ブロック陸部のタイヤ幅方向の外側側壁における隣接した2個の頂点の中間点Bとの間に位置している。
