Abstract
A tire includes a tread portion for contacting a road surface, two shoulder portions on each axial side of the tread portion, two sidewall portions extending radially inward from the shoulder portions, two hoop-shaped bead portions, and a carcass layer folded over the bead portions from an axially inner side to an axially outer side of the tire thus stretching the carcass layer into a toroidal shape in the tire circumferential direction of the first tire. One of the shoulder portions includes a recessed portion for modifying air flow about the one shoulder portion.
