PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To provide a pneumatic tire for improving uneven wear generated in circuit travel with large lateral acceleration in turning travel. SOLUTION: A block 7A having an obtuse angle-shaped corner part 5Y and an acute angle-shaped corner part 6 is dividedly formed of a circumferential groove 2B extending in the tire circumferential direction T arranged on the side of the tire center line CL in a center area 1A of a tread surface 1 for designating the tire rotational direction R in one direction and a lateral groove 3 slantingly extending toward the tire anti-rotational directional side to the tire width directional outside from the circumferential groove 2B and arranged at a prescribed pitch in the tire circumferential direction T. Both-side groove wall surfaces W2 and W3 of the obtuse angle-shaped corner part 5Y facing the circumferential groove 2B of the block 7A are inclined so that an inclinationαgradually becomes large toward the obtuse angle-shaped corner part 5Y, and the inclinationαbecomes maximum in the obtuse angle-shaped corner part 5Y.
