A pneumatic tire is provided with at least three circumferential main grooves extending in the circumferential direction of the tire and a plurality of land portions defined by the circumferential main grooves. Additionally, the belt layer is formed by layering a pair of cross belts having a belt angle, as an absolute value, of no less than 10° and no more than 45° and having a belt angles of mutually opposite signs, and a circumferential reinforcing layer having a belt angle within a range of ±5° with respect to a circumferential direction of the tire. A tire ground contact width (Wg) and a carcass cross-sectional width (Wca) of a carcass layer have a relationship such that 0.64≤Wg/Wca≤0.84.
