PURPOSE: To Provide a pneumatic tire whose drain performance particularly at cornering travel time is enhanced while maintaining excellent drain performance of a directional pattern. CONSTITUTION: A first or second inclined main grooves 2 or 3 inversely inclined to the tire circumference is arranged in a tread part 1 of a tread. The first inclined main groove 2 is arranged at an angle of 10 to 30 deg. to the tire circumference, and has a straight line-shaped steeply inclined part 2b extending toward the first tread end 4a positioned inside (6) of a vehicle, and the second inclined main groove 3 extends in a curve shape by crossing the first inclined main groove 2, and an angle formed by a tangent drawn in this second inclined main groove 2 and the tire circumference gradually increases in a range of 20 to 80 deg. as it proceeds in the direction of the second tread end 4b from the starting end 3a. |
