PNEUMATIC TIRE

A pneumatic tire (1) has a tread portion (2) provided with shoulder blocks (4) arranged along the tread edges and each having a side surface (4S) extending radially inwardly from the tread edge. The side surface (4S) includes a first surface section (15) and a second surface section (16) arranged in the tire (1) circumferential direction and protruding outward of the tire (1) than the groove bottom (3S) surfaces of the shoulder lateral grooves (3). In a tire (1) meridian section including the first surface section (15), the profile line (J2) of the first surface section (15) extends from the tread edge to a position corresponding to a position of the radial inner ends of the shoulder lateral grooves (3). In a tire (1) meridian section including the second surface section (16), the profile line (J2) of the second surface section (16) 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 (1) than that of the profile line (J2) of the first surface section (15).
