Title
(EN) Pneumatic tire
(ZH) 充气轮胎
Abstract
(EN)
A pneumatic tire maintaining excellent traction performance for the entire life of the tire. The tire (10) has blocks (18) each demarcated by both a circumferential groove formed in the tread and lateral grooves crossing the circumferential groove, and also has recessed parts (20). Each recessed part (20) is formed in at least one of those both wall surfaces of each block (18) that are oriented to the lateral direction of the tire, and the circumferential width (C) of each recessed part (20) is increased from the tread side of the block (18) toward the radially inside of the tire. Because the edge effect of the blocks (18) at the portions between the lateral grooves and the recessed parts (20) can be maintained in an excellent state even if the wear of the tire (10) progresses, the edge effect of the entire blocks can be maintained in an excellent state, and excellent traction performance can be maintained for the entire life of the tire.

本发明提供一种在轮胎整个使用期间中保持良好的牵引性能的充气轮胎。轮胎(10)包括:设于胎面的周向槽;由周向槽和与周向槽交叉的宽度方向槽划分形成的块(18);设于块(18)的轮胎宽度方向侧的两壁面中至少一方、自上述块(18)的接地面侧朝向轮胎径向内侧而周向宽度(C)增大的凹部(20)。即使轮胎(10)进行磨耗,块(18)的、宽度方向槽与凹部(20)之间的部分的边缘效应也被保持为良好的状态,因此作为块整体的边缘效应被保持为良好的状态、在轮胎整个使用期间中保持良好的牵引性能。
