PURPOSE:To provide a pneumatic tire, in which a high traction can be maintained until end of abrasion while suppressing the generation of uneven abrasion in a tire provided with a block pattern, for a heavy load. CONSTITUTION:In a pneumatic tire, in which plural main grooves 1 extending to the tire circumferential direction and plural lateral grooves crossing the main grooves 1 are provided in a tread face and plural blocks 3 partitioned by the main grooves and the lateral grooves are formed, for a heavy load, raised bottom parts 4 are provided inside the lateral grooves 2 between the blocks 3 lining up in the tire circumferential direction, while at least one narrow groove 5 and narrow ribs 6, which are divided by the narrow groove 5, are formed along the tire circumferential direction on the surface of the raised bottom part 4. |
