Abstract
Provided is a pneumatic tire. Both terminals of a carcass layer are overlapped with each other in a tread region. The carcass layer has a triple layer structure including an inner layer positioned most inward in a tire radial direction in the tread region, an outer layer positioned most outward in the tire radial direction in the tread region, and an intermediate layer positioned between the inner layer and the outer layer in the tread region. A cord angle in the carcass layer in a tread central region with respect to a tire circumferential direction differs in at least one of the inner layer, the outer layer, and the intermediate layer from a cord angle in the carcass layer in a side region with respect to the tire circumferential direction.
