Abstract
A pneumatic tire includes a center land portion, intermediate land portions, and shoulder land portions each with sipes arranged at intervals in a circumferential direction. Center land sipes have a widened portion with a wide groove width at one end. Shoulder land sipes extend from the outer side of a ground contact end in a lateral direction toward an outer main groove. The orientation of the center and shoulder land sipes with respect to the circumferential direction is opposite to the orientation of intermediate land sipes. Respective inclination angles θ, θ, θof the center, intermediate and shoulder land sipes satisfy θ<θ<θ<90°, an end of the intermediate land sipe on the side of the inner main groove is between ends of the center land sipes, and at any position on the entire circumference at least one center or intermediate land sipe is present on a meridian.
