A pneumatic tire (2) includes a tread (4), a sidewall (6), a bead (8), a carcass (10), a belt (12), a band (14), a reinforcing layer (16), and an inner liner (18). The tread (4) has a shoulder main groove (24). The reinforcing layer (16) is present locally in an axial direction. The reinforcing layer (16) is positioned between the carcass (10) and the belt (12) in a radial direction. The reinforcing layer (16) is positioned on an inside in the radial direction with respect to the shoulder main groove (24). The reinforcing layer (16) is formed by a large number of cords provided in parallel and a topping rubber. The respective cords are extended substantially in the axial direction. A width (Wr) of the reinforcing layer (16) is equal to or higher than 200% of a width (Wg) of the shoulder main groove (24) and is equal to or lower than 500% of the width (Wg) of the shoulder main groove (24).
