Abstract
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.
