摘要： The present invention provides a pneumatic tire having a carcass as a skeleton extending in a toroidal shape over a pair of bead portions, a belt including at least one slant layer, and a tread, the belt and the tread being disposed on the outer side in the tire radial direction of a crown portion of the carcass in this order, characterized in that: a ratio BD/BW of radius difference BD between radius at the center portion and radius at an end portion in the tire widthwise direction of the outermost layer of the slant belt layer(s), to a width BW of the outermost layer, is in the range of 0.01 to 0.04 in a section of the tire in the widthwise direction in a state where the tire is assembled with an application rim. A pneumatic tire being excellent in wear resistance performance and having relatively low rolling resistance can be obtained accordingly.

摘要： It is an object of the present invention to provide a rim for a pneumatic tire that can suppress local deformation of the sidewall portion of a mounted tire and thus suppress the occurrence of damage to the sidewall portion. The rim for a pneumatic tire according to the present invention is provided with a pair of bead seat portions separated from each other in a rim width direction and a flange portion extending outwards in a rim radial direction from a rim width direction outer end of each bead seat portion. A rim radial direction outer end of the flange portion is recurved outwards in the rim width direction. A radius of curvature of a surface of the flange portion at a rim width direction outer end portion of the flange portion is at least 0.4 times and at most 1.0 times a radius of curvature of the surface of the flange portion at a rim width direction central portion of the flange portion.
