摘要： A pneumatic tire includes circumferential main grooves extending in the tire circumferential direction and arranged side by side in the tire width direction and a land portion defined by the circumferential main grooves. The land portion includes notch portions extending in the tire width direction and connected to the circumferential main grooves and shallow groove portions connected to the notch portions, respectively, and terminating in the land portion. The height of the notch portions decreases continuously toward the circumferential main grooves connected thereto.

摘要： The tire includes a tread portion having circumferential grooves extending in a tire circumferential direction and land regions demarcated by the circumferential grooves. The circumferential grooves include a first circumferential groove and a second circumferential groove adjacent to the first circumferential groove and having a width larger than the first circumferential groove. The land regions include a first land region demarcated between the first circumferential groove and the second circumferential groove. The first land region has lateral grooves extending in a tire axial direction and lateral sipes extending in the tire axial direction and each having a width smaller than that of each of the lateral grooves. A total value of the widths of the lateral grooves and the lateral sipes connected to the second circumferential grooves is smaller than a total value of the widths of the lateral grooves and the lateral sipes connected to the first circumferential grooves.

摘要： 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.

摘要： A tyre including a tread portion. The tread portion includes a ground contacting surface and at least one main groove recessed from the ground contacting surface and extending continuously in a tyre circumferential direction. At least one of groove walls of the main groove is provided with a recessed portion recessed outwardly in a groove width direction from a corresponding groove edge of the main groove on the ground contacting surface. The ground contacting surface has a protruding portion in a region where the recessed portion is projected outwardly in a tyre radial direction.

摘要： A tire (1) is provided with multiple projection parts (500) in a groove bottom (50B2) of a groove portion. The projection parts (500) extend from one side wall (50B1) to the other side wall (50B3) opposed to the one side wall (50B1), the side walls forming the groove portion. The projection parts (500) are arranged at predetermined intervals in the groove portion. A relationship of 0.75 L≦P≦10 L is satisfied where L denotes a length of the projection parts (500) and P denotes the predetermined intervals. In addition a relationship of 0.4≦FW/W

摘要： A tire is provided with multiple projection parts in a groove bottom of a groove portion. The projection parts extend from one side wall to the other side wall opposed to the one side wall, the side walls forming the groove portion. The projection parts are arranged at predetermined intervals in the groove portion. Lateral groove portions that extend from the groove portion to a buttress section, and have openings in the buttress section are formed. Air supply mechanisms that supply air to the lateral groove portions are formed.
