Abstract
PURPOSE:To prevent the generation of cracks on a cut edge part in brake application or driving, by setting the depth of a cut formed on a tread rubber layer within a specific range and arranging the cut edge part at the position having a high rigidity where a stress hardly acts. CONSTITUTION:As for a tread rubber layer 1 of a tire, longitudinal grooves 2 and cut parts 3 are formed on the surface, and a belt reinforced layer 4 is installed inside. In this case, the cut part 3 is formed as the cut crossing a bulged part between the longitudinal grooves 2, having an inclination angle thetaof 30-90 deg. with respect to the longitudinal groove 2, and keeping an interval P of 10-50mm in the circumferential direction. The depth of the cut 3 is set so that the cut edge part 3a is positioned at the part where the stress in the tread rubber layer 1 hardly acts. In other words, when the depth of the cut 3 is set C, depth of the longitudinal groove 2 is set D, thickness from the bottom surface 2a of the longitudinal groove 2 to the belt reinforced layer 4 is set S, the following relation shall be satisfied; D+S/2>=C>=0.95D.
