<p>PROBLEM TO BE SOLVED: To suppress occurrence of noise while keeping wet performance.SOLUTION: In a pneumatic tire, outer side vertical grooves 12a and 12b extend zigzag in the tire circumferential direction, and a plurality of lateral grooves 13a and 13b positioned in the outer part 14 of the tread part 11 extend gradually toward one side in the tire circumferential direction S as extending from the outer side to the inner side in the tire width direction H and are connected to outer longitudinal grooves. A plurality of second lateral grooves 13c and 13d positioned in the inner part 15 of the tread part extend gradually toward one side in the tire circumferential direction as extending from the inner side to the outer side in the tire width direction and are connected to the outer longitudinal grooves. The positions of the plurality of the first lateral grooves in individual tire circumferential directions in the outer part and the positions of the plurality of the second lateral grooves in individual tire circumferential directions in the inner part coincide with one another, and the inclination anglesθ1 andθ2 of the first and second lateral grooves to the tire width direction are the same and 10-25°.</p> |
