PROBLEM TO BE SOLVED: To improve noise performance and mud performance in well balanced manner.SOLUTION: Shoulder lateral grooves 8 include first shoulder lateral grooves 14 and second lateral grooves 15. Each of the first shoulder lateral groove 14 and the second shoulder lateral groove 15 includes: an inner part 16 extending from a shoulder main groove 3 at a first angle &thetas;1; an intermediate part 17 connected to the inner part 16, and extending at a second angle &thetas;2 larger than the first angle &thetas;1; and an outer part 18 connected to the intermediate part 17, and extending at a third angle &thetas;3 smaller than the second angle &thetas;2. The intermediate part 17 of the first shoulder lateral groove 14 is positioned on a tire-axis-direction inner side of the intermediate part 17 of the second shoulder lateral groove 15. The first shoulder lateral groove 14 and the second shoulder lateral groove 15 are alternately formed in the tire circumferential direction. |
