A pneumatic tire includes a tread surface (11) on which a plurality of circumferential groove portions (50) is formed. From among the circumferential groove portions (50), a circumferential groove portion (50) situated closest to a shoulder portion side (42) in a tire width direction has a center of a groove-bottom innermost portion at a portion where a groove width in at least a tire circumferential direction is the narrowest, positioned closer to an equatorial surface (90) in the tire width direction than a center of the groove width. An angle between a virtual extension portion (80) of the tread surface (11) and a groove wall (60) on the equatorial surface side (90) is equal to or less than an angle between the virtual extension portion of (80) the tread surface (11) and a groove wall (60) on the shoulder portion side (42). |
