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. The present invention is a tire (1) having a tread portion (2). A plurality of circumferential grooves (4) extending in the tire circumferential direction are formed in the tread portion (2). When a normal load is applied at a camber angle of 0 DEG in a normal state in which a normal rim is assembled and adjusted to a normal internal pressure, a ground contact surface (2a) of the tread portion (2) has a ground contact length (L), which is a length in the tire circumferential direction in relation to each position (P) in the tire axial direction. The circumferential groove (4) has a groove depth (d) proportional to a ground contact length (L) at a position (P) forming the circumferential groove (4) in the axial direction of the tire.
本发明提供一种维持优异的耐磨损性能并能提高噪声性能的轮胎及该轮胎的沟深设定方法。本发明是具有胎面部(2)的轮胎(1)。在胎面部(2)形成有沿轮胎周向延伸的多个周向沟(4)。胎面部(2)在对正规轮辋进行轮辋组装并调整为正规内压的正规状态下以0°的外倾角加载了正规载荷时的接地面(2a)具有与轮胎轴向的各个位置(P)相关的轮胎周向的长度亦即接地长(L)。周向沟(4)具有与形成周向沟(4)的轮胎轴向的位置(P)处的接地长(L)成比例的沟深(d)。
