The invention provides a tire capable of maintaining excellent wear resistance and improving noise performance, and a method for setting the groove depth of the tire. A tire (1) has a tread portion (2). A plurality of grooves (3) are formed in the tread portion (2). The tread portion (2) has a ground contact surface (2a) having a ground contact length (L), which is a length in the circumferential direction of the tire with respect to each position (P) in the axial direction of the tire, when a normal load is applied at a camber angle of 0 DEG in a normal state in which the tire is assembled to a normal rim and adjusted to a normal internal pressure. The groove (3) has a groove depth (d) that is equal to or less than a length proportional to a ground contact length (L) at a position (P) where the groove (3) is formed in the tire axial direction.

    本发明提供一种能够维持优异的耐磨损性能并且提高噪声性能的轮胎以及该轮胎的沟深设定方法。轮胎(1)具有胎面部(2)。在胎面部(2)形成有多条沟(3)。胎面部(2)在轮胎组装于正规轮辋并且调整为正规内压的正规状态下以0°外倾角加载了正规载荷时的接地面(2a)具有与轮胎轴向上的各个位置(P)相关的轮胎周向上的长度亦即接地长(L)。沟(3)具有与轮胎轴向上的形成沟(3)的位置(P)处的接地长(L)成比例的长度以下的沟深(d)。
