Abstract:
A pneumatic tire is provided. A tread portion includes shallow grooves formed in a road contact surface of each of shoulder blocks, intermediate blocks, and center blocks, defined by a plurality of longitudinal grooves extending in a tire circumferential direction and a plurality of lateral grooves extending in a tire lateral direction, the shallow groove having a smaller groove depth than the longitudinal groove and the lateral groove. The shallow groove extends along the tire lateral direction, and at least one end thereof communicates with the longitudinal groove or the lateral groove. A contour line of the shallow groove is provided with at least one bend point. A sipe is provided in a flat bottom surface of the shallow groove extending along the shallow groove. Among the shallow grooves, center shallow grooves formed in the center block are each provided with a terminating end portion terminating in the center block.
