PNEUMATIC RADIAL TIRE FOR VEHICLE

摘要: PROBLEM TO BE SOLVED: To provide a pneumatic tire for vehicle that is improved in wet performance and roll resistance as narrow-width, large-diameter radial tire.SOLUTION: When rim incorporated 1 internal pressure 250 kPa or larger, ratio SW/OD of sectional width SW the to an outer diameter OD (mm) satisfies less than 0.26 165 2.135×SW+282.3≤OD larger. Tread rubber has dynamic storage elastic modulus E' 6.0-12.0 MPa loss tangent tanδ 0.05-0.15. A plurality sipe 9 are arranged at least one land part 8 predetermined pitch length L, 0.6 W≤Ws≤1.2 W L≤Ls≤3 L hold W, width-directional component total Ws sipes within range periphery-directional Ls L.SELECTED DRAWING: Figure 2
