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 at the outside relative to a vehicle and an inside rubber having a relatively low tension modulus is arranged at the inside relative to a 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: Mo - Mi / Mo ‰¥ 0.15 Ho - Hi ‰¤ ± 3 �¢ ° .",
