Abstract:
Disclosed is a pneumatic tire which is provided, in the center of the tread surface, with a center rib (6) extending along the circumferential direction of the tire. Specifically disclosed is a pneumatic tire wherein the width (Rw) of the center rib (6) is not less than 10% of the grounding width (Cw), and an outer rubber (5o) having a relatively high tensile modulus is arranged on the outer side of a vehicle and an inner rubber (5i) having a relatively low tensile modulus is arranged on the inner side of the vehicle while having an interface (10) formed in the center rib (6) along the radial direction of the tire as the boundary. The 300% tensile modulus (Mo) and the rubber hardness (Ho) of the outer rubber (5o), and the 300% tensile modulus (Mi) and the rubber hardness (Hi) of the inner rubber (5i) satisfy the following relations; (Mo-Mi)/Mo≥0.15, and Ho-Hi≤±3°.
