PROBLEM TO BE SOLVED: To provide a pneumatic tire whose tread blocks are improved in rigidity along a circumference direction.SOLUTION: In the pneumatic tire, a second group is formed deeper than a first group to approximate a first block to a second block so as to make rigidity of the first block almost identical to rigidity of the second block, and a first angle is formed larger than a second angle to make rigidity of the first block almost identical to rigidity of the second block. This has effects of making rigidity of the tire uniform along a circumference direction of the tire so that brake performance or grip performance of the tire is improved. |
