When a tire is attached to a rim and set to an internal pressure of 250 kPa or more, a ratio SW/OD of the tire is 0.26 or less in the case where SW of the tire is less than 165 (mm), and SW and OD satisfy a relationship 2.135×SW+282.3≦OD in the case where SW is 165 (mm) or more. The tread rubber has dynamic storage modulus E′ of 6.0 MPa to 12.0 MPa, and loss tangent tan δ of 0.05 to 0.15. In at least one land portion, sipes are arranged with a predetermined pitch length L, and a land portion width W, a tire widthwise sipe component total length Ws of the sipes, the pitch length L, and a tire circumferential sipe component total length Ls of the sipes satisfy relationships 0.4W≦Ws≦1.2W and 0.6L≦Ls≦3L.
