PROBLEM TO BE SOLVED: To provide a pneumatic tire that can improve traction performance and handling performance on a snow road.SOLUTION: A main groove includes an outer shoulder main groove 3 which extends zigzag at an outer tread end Teo side and an outer center main groove 4 which extends zigzag at an inner tread end Tei side, inner than the outer shoulder main groove 3. The outer shoulder main groove 3 has: a plurality of first shoulder inclined parts 7 which are inclined toward the outer tread end Teo at an angle θa relative to a tire circumference direction; and a plurality of second shoulder inclined parts 8 which are inclined at an angle θb larger than the angle θa, relative to the tire circumference direction, in the same direction as the direction of the first shoulder inclined parts 7, and have lengths smaller than the first shoulder inclined parts 7. The first shoulder inclined parts 7 and the second shoulder inclined parts 8 are arranged alternately in a tire circumference direction. The first shoulder inclined parts 7 gradually increase in a groove width as approaching the outer tread end Teo side.SELECTED DRAWING: Figure 1 |
