A passenger vehicle pneumatic tire having sufficiently improved wet performance is provided. When the tire is applied with an internal pressure of 250 kPa or more, a ratio SW/OD between a sectional width SW and an outer diameter OD (mm) of the tire is 0.26 or less in the case where the sectional width SW is less than 165 (mm), and the sectional width SW and the outer diameter OD (mm) satisfy a relational expression: 2.135 × SW + 282.3 ‰¤ OD in the case where the sectional width SW is 165 (mm) or more. At least part of a portion of a tread rubber located at a tread rubber surface thereof has a dynamic storage modulus E' of 4.0 MPa or more, and is made of a rubber composition including: a rubber component (A) containing 50 mass% or more of diene-based rubber; and, with respect to 100 parts by mass of the rubber component (A), 5 to 50 parts by mass of at least one additive component (B) selected from: thermoplastic resin; oil; and a low-molecular-weight aromatic vinyl compound-conjugated diene compound copolymer.
