发明名称 PNEUMATIC TIRE
摘要 PROBLEM TO BE SOLVED: To provide a pneumatic tire which reduces rolling resistance, and which is excellent in partial wear performance when it is mounted on a vehicle by imparting a camber.SOLUTION: A pneumatic tire includes a first belt layer 7 in which a cord having an angle to a tire equatorial plane of 15-75° is extended, and a second belt layer 8 in which a cord having an angle of 0-5°C is extended. In the second belt layer 8, the intermediate elongation of a second cord is 0.2-2.5%, and relation of 0.003<&delta;/Rs<0.02 is satisfied, where Rs is a radial direction length from a tire shaft to the tire equatorial plane S of the second belt layer 8, Re is a radial direction length Re to width direction outmost end, and &delta; is a difference between Rs and Re, and relation of Gs<Gc is satisfied, where Gc is a tread rubber gauge at the tire equatorial plane S of the belt layer located in a tire radial direction outside, and Gs is a tread rubber gauge at the width direction outmost end.
