A groove depth of the circumferential groove can be 21 mm or more. Each of the hexagonal blocks can include a three-dimensional sipe extending across the hexagonal block. The lateral groove can include a raised portion formed by raising a groove bottom of the lateral groove to connect between the hexagonal blocks adjacent to each other in the tire circumferential direction.
