Abstract: A pneumatic tire includes a tread having a center main groove and a pair of shoulder main grooves, a pair of center portions between the center main groove and the shoulder main grooves, and a pair of shoulder portions between the shoulder main groove and tread edges. Each center portion includes: center lateral grooves extending from the shoulder main groove toward the axially inside of the tire without reaching the center main groove so as to have an axially inner end thereof on the center portion with an angle of 35 to 65 degrees with respect to an axial direction of the tire; center lateral sipes extending from axially inner ends of the center lateral grooves to the center main groove in the same inclination direction as the center lateral groove at an angle of 35 to 65 degrees with respect to an axial direction of the tire.
