PNEUMATIC TIRE

A pneumatic tire includes block rows which are arranged in a tire width direction and each of which includes a plurality of blocks defined by main grooves extending in a tire circumferential direction and lateral grooves extending in a tire width direction. The plurality of block rows includes inner block rows which are the block rows other than an outermost block row located most outwardly in the tire width direction. Numbers of the blocks included in the inner block rows increase toward an inner side in the tire width direction. The blocks in each of the inner block rows include an auxiliary-grooves-formed block having, on an outer surface thereof, an auxiliary groove region in which a plurality of drain auxiliary grooves extending in the tire circumferential direction are formed. Occupied areas in each of the inner block rows decrease toward the inner side in the tire width direction.
