In other refers, it is a portion that would be particularly strong grounding shoulder - portion adjacent to the block 4 1 tread edge E A
And while the portion B adjacent to the circumferential main grooves 2 1 and adjacent the intermediate block 4 2 the main grooves 2 1, and in particular play a large road surface reaction force, shoulder - block 4 1 of the circumferential main portion C adjacent to the groove 2 1 will be lifted from the road surface. As a result, the ground contact pressure of the block becomes high A, B
Is significantly worn, whereas the part C where the ground pressure hardly acts remains without being worn, and uneven wear occurs relatively early, which shortens the life of the tire and causes vibration, This leads to deterioration of maneuverability such as steering stability.

In order to solve this problem, the width of the circumferential groove is narrowed to the extent that both groove walls contact each other when a lateral force is applied, and the deformation of the tire is restrained under the contact of both groove walls. Therefore, an attempt was made to improve the wear mode, but in this case, it was unavoidable that the drainage performance on the wet road surface was lowered due to the reduction of the groove volume of the tread. The present invention advantageously solves the above problems of the prior art, and an object of the present invention is to provide a pneumatic tire capable of sufficiently preventing the occurrence of uneven wear without lowering the drainage property. To do.

The tire according to the present invention is provided with a shoulder block row between the tread end and a central block row on the inner side in the axial direction with the circumferential main groove as a boundary, and each block in the shoulder block row is The edge portion facing the circumferential main groove is formed of rubber that is harder than the remaining portion of the block. Therefore, as shown in FIG. 2 (b), when a large lateral acceleration is applied during high-speed turning traveling, the shoulder block is prevented from being deformed or collapsed inward in the axial direction by the reinforcement by the hard rubber. As a result, lifting of the shoulder block C is prevented, and at the same time, excessive ground pressure at the B portion of the intermediate block separated by the circumferential groove is reduced, and abnormal wear of that portion is effectively reduced.
