摘要： A pneumatic tire having improved wear resistance, especially improved uneven wear resistance (such as river wear), is offered. The tire that is a rib-pattern tire has five ribs extending circumferentially of the tire. The ribs include a center rib and intermediate ribs located on the opposite sides of the center rib that is located on the equator line of the tire. Closed sipes are formed at least in the center rib and in the intermediate ribs. Each sipe is located in the lateral center of the corresponding rib. Both ends of each sipe terminate within the corresponding rib. The closed sipes are successively offset circumferentially among the ribs and arranged in a periodic pattern on the outer surface of the tire. The closed sipes in the ribs are so arranged that when they are optically projected onto the equator line of the tire, the sipes do not overlap circumferentially of the tire among the ribs.

摘要： A pneumatic tire has a pair of bead portions, side wall portions extending to an outer side in a tire diametrical direction from the bead portions, and a tread portion connected to an outer end in a tire diametrical direction of each of the side wall portions. An outer wall surface of the side wall portion is provided with a circumferential projection annularly extending along a tire circumferential direction, and a plurality of diametrical projections extending to an inner side in a tire diametrical direction from the circumferential projection and arranged so as to be spaced in the tire circumferential direction. A gap portion formed between the diametrical projections is open to an inner side in the tire diametrical direction.
