PROBLEM TO BE SOLVED: To suppress reduction of comfortable riding property and operation stability to a low degree while exhibiting excellent rolling resistance performance in use of a tire with high internal pressure. SOLUTION: In the normal internal pressure state, tread ground-contact width TW is made to 0.55-0.65 times the nominal width of the tire and width BW of a belt ply 7A of the maximum width is made larger than 1.0 time and 1.2 times or less the tread ground-contact width TW. In a state of internal pressure of 300 kPa, a camber amount Ca, i.e., a tire radial distance from a tire equator point Cp on a tread surface 2S to a tread ground-contact end Te is made 0.045-0.070 times the tread ground-contact width TW.
