<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire having improved driving stability performance while maintaining wet performance and rolling resistance performance.SOLUTION: The pneumatic tire has a tread part 2 provided with a major groove 10 and a lateral groove 20. Groove wall faces 16 on both sides of the major groove 10 are formed of arcuate faces with a curvature radius R1 of becoming convex toward a groove center 10c side. Groove wall faces 26 on both sides of the lateral groove 20 are formed of arcuate faces with a curvature radius R2 of becoming convex toward a groove center 20c side. The curvature radius R2 of the groove wall faces 26 of the lateral groove 20 is greater than the curvature radius R1 of groove wall faces 16 of the major groove 10.</p> |
