Abstract
To provide a pneumatic tire capable of improving the rolling performance, low noise performance and wear resistance performance while maintaining the wet performance. It is a pneumatic tire () provided in the tread portion () with a plurality of main grooves (). The main groove () has, in a cross-section perpendicular to the longitudinal direction of the groove, a first groove bottom (A) and a pair of first groove walls (B,B) extending smoothly from the first groove bottom (A) to the tread surface (S). In the main groove (), the width (W) between the first groove walls (B) is 2.0 to 20.0 mm at a tread surface (S), and the depth (D) from the tread surface (S) to the first groove bottom (A) is 10.0 mm or more. In the first wall (B), the ratio (W/α) of the angle (α) [degree] with respect to a normal direction to the tread surface (S) and the width (W) [mm] is in a range of 1.0 to 2.0 [mm/degree].
