A high performance tire, in which the profile of radially outer ground contacting tread surface is radially outwardly expanded at both shoulder parts when the tire is inflated, and the tread pattern circumferential stiffness as well as index of groove volume is optimized so that resistance in wear, durability to high speed running (low degree of heat generation), resistance to cutting, and resistance to rolling (low fuel consumption) including wet grip performance and stability in vehicle driving may be advantageously improved without reducing comfortableness in vehicle riding. |
