A plurality of circumference direction primary grooves which extend in the tire circumference direction are formed in a tread part (16). Outer side ribs (46) which communicate with land parts in the tire circumference direction are formed further on the vehicle outer side when the tire is mounted than the plurality of circumference direction primary grooves.
