A pneumatic tire with a specified rotational direction includes a tread portion provided with a pair of circumferentially extending crown main grooves disposed on both sides of the tire equator, a plurality of inclined lateral grooves each extending axially outside of the tire from each crown main groove to each tread edge toward the anti-rotational direction to separate a plurality of shoulder blocks between crown main grooves and tread edges, and a sipe, inclined lateral grooves with inclinations of 45-85 degrees with respect to the tire circumferential direction, each shoulder block with a heel-side edge and a toe-side edge which comes into contact with a road later than the heel-side edge in the specified rotational direction, in a planer view, the heel-side edge smoothly extending in a curved manner from a first end intersecting a groove wall of the crown main groove to a second end intersecting the tread edge.
