1. A pneumatic tire comprising a carcass layer, a belt layer disposed outward in a tire radial direction of the carcass layer, and a tread rubber disposed outward in the tire radial direction of the belt layer, wherein
the belt layer is formed by laminating a pair of cross belts having a belt angle of not less than 10° and not more than 45° in absolute values and having belt angles of mutually opposite signs, and a circumferential reinforcing layer having a belt angle within a range of ±5° with respect to the tire circumferential direction, a tread width TW and a total tire width SW have a relationship such that 0.79≦TW/SW≦0.89, and a highest position diameter Ya of the carcass layer, a height position diameter Yb of the carcass layer at an end portion of the circumferential reinforcing layer, and a widest position diameter Yc of the carcass layer have relationships such that 0.80≦Yc/Ya≦0.90 and 0.95≦Yb/Ya≦1.00. |
