PROBLEM TO BE SOLVED: To improve draining performance while maintaining at least steering stability and snow traction performance, in a pneumatic tire.SOLUTION: A tread pattern includes outer main grooves and inner main grooves extending in a tire circumferential direction, and first inclined lug grooves and second inclined lug grooves provided in regions held between the outer main grooves and the inner main grooves. The first inclined lug grooves and the second inclined lug grooves extend in a first direction of the tire circumferential direction on the outside in the tire width direction from internal positions in an intermediate region without being opened to the inner main grooves. The first inclined lug grooves are opened to one of the outer main grooves, and the second inclined lug grooves are blocked without being opened to the outer main grooves. Each of the second inclined lug grooves has an inclined portion with a small inclination angle in the tire circumferential direction compared with the first inclined lug grooves, and the inclined portion of each second inclined lug groove crosses at least two of the first inclined lug grooves. |
