<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of striking a balance between the maintenance of maneuvering stability and the reduction of rolling resistance. <P>SOLUTION: This pneumatic tire 100 includes a carcass 4 extending in a toroidal shape and forming a tire skeleton and a crossing belt 5 on the outside in the tire radial direction of the carcass 4 in a tread 1, and designates the inside and the outside installed in a vehicle. In surfaces of sidewalls, R1>R2 is satisfied, when assuming curvature radii of curved portions in buttress portions 6a and 6b on the outside and inside installed in the vehicle when viewed in a cross section in the tire width direction, as R1 and R2, respectively. Heights H1 and H2 of maximum width positions 7a and 7b of the sidewalls are H1<H2. In the crossing belt, an inclination of a cord to the tire equator CL in a belt layer 5b on the outermost side in the tire radial direction, is the direction for approaching the cord to the vehicle center line Vc toward the inside from the outside installed in the vehicle when viewed from above the vehicle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
