PROBLEM TO BE SOLVED: To provide a pneumatic tire that achieves both wet performance and steering stability.SOLUTION: In the pneumatic tire, a pair of shoulder main grooves 3 and at least one center main groove 4 are provided at a tread part 2 so that a pair of middle land parts 10 are partitioned. In the middle land parts 10 are alternately provided inner middle lug grooves 11 and outer middle lug grooves 12 in a tire circumference direction. Each inner middle lug groove 11 is communicated with the center main groove at angles &thetas;1 of 20 to 45° relative to the tire circumference direction. Each outer middle lug groove 12 is communicated with the shoulder main groove 3 at angles &thetas;2 of 60 to 80° relative to the tire circumference direction. |
