Abstract
Groove widths of center main grooves are larger than groove widths of inner and outer main grooves. Plurality of lateral grooves are formed at intervals in a tire circumferential direction so as to define inner shoulder blocks belonging to an inner shoulder row. A first raised portion connecting a pair of inner shoulder blocks to each other is formed in the lateral grooves every one other on an inner main groove side. A depth of the lateral groove in the first raised portion is smaller than the depth of the lateral groove in other portions. A second raised portion is formed on the outer main groove in a region defined by an imaginary line connecting an outer intermediate block and an outer shoulder block. A depth of the outer main groove in the second raised portion is smaller than that of the outer main groove in other portions.
