Abstract

A pneumatic tire has a center rib extending along a tire circumferential direction in a center portion of a tread surface. A width of the center rib is equal to or more than 10% of a grounding width. An outside rubber having a relatively high tension modulus is arranged outside a vehicle and an inside rubber having a relatively low tension modulus is arranged inside the vehicle, by setting an interface formed in the center rib along a tire diametrical direction to a boundary. 300% tension modulus Mo and a rubber hardness Ho of the outside rubber, and 300% tension modulus Mi and a rubber hardness Hi of the inside rubber satisfy the following relationship:
