In a tire 2, a cap layer 30 of a tread 4 includes a center element 32 and a pair of side elements 34. Each side element 34 is more flexible than the center element 32. A plurality of lateral grooves 60 each having a groove width of 2.0 mm or greater are formed on each shoulder land portion 58s of the tread 4. In a ground-contact surface obtained by pressing the tire 2 in a normal state against a road surface at a load equal to 68% of a normal load, a ratio of areas of the lateral grooves 60 included in a ground-contact surface of the shoulder land portion 58s to an area of the ground-contact surface of the shoulder land portion 58s is not greater than 3%. The cap layer 30 in the shoulder land portion 58s includes the side element 34.
