Abstract

A pneumatic tire (1) comprises a tread (50),iSide walls (60), and buttress portions (70). In a cross-section of the pneumatic tire (1) in the tread width direction (TW), if the point at which a first curved line (Rl) which follows the curvature of the surface of the tread (50) and a second curved line (R2) which follows the curvature of the surface of a buttress portion (70) intersect is defined as an imaginary point (IP) and also if the point at which a straight line (L) passing through the imaginary point (IP) and substantially perpendicular to the carcass (20) intersects the surface of the pneumatic tire (1) is defined as an intersection point (NP), the pneumatic tire (1) has a recessed shoulder region (US) including the intersection point (NP) and having a predetermined width. The recessed shoulder region (US) is provided with recesses (80) recessed from the surface of the pneumatic tire (1) and also with a surface portion (90) in which no recess (80) is formed. The recessed shoulder region (US) extends in the tire circumference direction (TC).
