When the passenger-vehicle pneumatic radial tire of the disclosure is assembled to a rim and filled with an internal pressure of 250 kPa or more, an SW/OD ratio is 0.26 or less if the tire has a sectional width SW of less than 165 (mm), whereas a sectional width SW and an outer diameter OD (mm) of the tire satisfy a relation of 2.135×SW+282.3≦OD if the tire has a sectional width SW of 165 (mm) or more, a dynamic storage modulus E′ at 30° C. of the tread rubber is 6.0 MPa to 12.0 MPa and a loss tangent tan δ at 60° C. of the tread rubber is 0.05 to 0.15, and a dynamic storage modulus E′ at 30° C. of the buttress rubber is ½ or less, and a loss tangent tan δ at 60° C. of the buttress rubber is 0.1 or less.
