Abstract

A tire comprises center blocks (4) comprising a first center lateral groove (5A) and a second center closed sipe (6a) opposed to each other in a tire axial direction, and a second center lateral groove (5B) and a first center closed sipe (6b) axially opposed to each other. Lengths thereof satisfy the followings: LA/LA0 ¤ 1/2, LB/LB0 ¤ 1/2, Lb/Lb0 in a range of from 1/3 to 2/3, La/La0 in a range of from 1/3 to 2/3, LA <La, (LA + La) <LA0, LB <Lb, and (LB + Lb) <LB0. The center blocks (4) comprise a high rigidity region extending continuously between penetrating sipes (3) and between a first imaginary line passing through terminating ends of the first center lateral groove and the first center closed sipe and a second imaginary line passing through terminating ends of the second center lateral groove and the second center closed sipe.
