PNEUMATIC TIRE

A pneumatic tire has a tread portion provided with shoulder blocks arranged along the tread edges and each having a side surface extending radially inwardly from the tread edge. The side surface includes a first surface section and a second surface section arranged in the tire circumferential direction and protruding outward of the tire than the groove bottom surfaces of the shoulder lateral grooves. In a tire meridian section including the first surface section, the profile line of the first surface section extends from the tread edge to a position corresponding to a position of the radial inner ends of the shoulder lateral grooves. In a tire meridian section including the second surface section, the profile line of the second surface section extends from the tread edge to a position corresponding to the above-said position of the radial inner ends through a path inward of the tire than that of the profile line of the first surface section.
