Abstract
A pneumatic tire comprises a carcass layer, a belt layer radially outward of the carcass layer, and a tread rubber radially outward of the belt layer. A belt cord angle of a belt layer large angle belt is 45-70°, opposite sign belt cord angles of cross belts are 10-45°, and a reinforcing layer belt cord angle is within ±5° of a circumferential direction. A reinforcing layer width Ws and a carcass cross-sectional width Wca satisfy 0.60≤Ws/Wca≤0.70. The reinforcing layer is radially outward of the cross belts which are radially outward of the large angle belt. A wider cross belt width Wbof the pair and Wca satisfy 0.79≤Wb/Wca≤0.89. Wb2 and Wca satisfy 0.79≤Wb/Wca≤0.89. Relationships 0.79≤Wb/Wca≤0.84 and either 0.82≤TW/Wca≤0.92 or 0.79≤TW/SW≤0.89 are satisfied, where TW is a tread width and SW is a total tire width.
