TIRE HAVING SHOULDER BLOCK

摘要

PURPOSE:To enhance the turning performance and/or the straight driving performance of a tire not only at a specific steering angle but also at other angles by arranging edges adjacent to each other in the circumferential direction of the tire, one of the edges being inclined at a desired angle to the axis of the tire and the other inclined at other than that angle. CONSTITUTION:A block pattern having a number of blocks 4 aligned in the circumferential direction C of the tire is formed in the center portion 2 and right and left shoulder portions 3 of a tread. Each block 4 has edges 5 formed at its front and rear ends extending in the circumferential direction C of the tire and at the front and rear ends of its surface on which sipes 6 are formed. Some of the blocks 4 have their edges 5 inclined at an angle A1 to the axis B of the tire and the blocks 4 located between have their edges 5 formed at angles A2-A5 other than angle A1.
