Abstract
The present invention ensures a large burst pressure without a large weight increase, while also limiting taxi wear and touchdown wear. In a first reference state, 0 ≤ δ35 / Rc ≤ 0.004 and 0.015 ≤ δ90 / Rc ≤ 0.025 are satisfied. Belt layers (5a to 5i) include two or more spiral belt layers (51) and one or more zigzag belt layers (52). The two or more spiral belt layers (51) include: a first spiral belt layer (511) having a tire widthwise edge (51c) located at a tire widthwise position farther outward in the tire widthwise direction than a shoulder circumferential groove (812); and a second spiral belt layer (512) having a tire widthwise edge (51c) located at a tire widthwise position between a center circumferential groove (811) and the shoulder circumferential groove (812).
