In a pneumatic tire, an intermediate land portion is provided with a plurality of lug grooves having acute bent portions and a plurality of sipes extending in a direction that intersects with the lug grooves. The lug grooves are disposed so as not to overlap one another in the tire circumferential direction, and each have one end that opens to an outer main groove and an other end that terminates in the intermediate land portion. When pitches, which serve as reference positions, are defined based on end points at which the lug grooves open to the outer main groove, the sipes each are disposed to be located inside one of the pitches, and the groove area ratio in the pitches in the intermediate land portion is in the range from 15% to 25%.
