Abstract:
A tread portion of a tire 1 to be mounted to a front wheel is divided in the tire widthwise direction into three regions comprising the center tread region A and respective shoulder tread regions C. Two types of tread rubber are used for the tread portion of the front tire. JIS-A hardness of tread rubber of the center tread region A is larger than JIS-A hardness of tread rubber of each shoulder tread region C. A tread portion of a rear tire 11 is divided in the tire widthwise direction into five regions comprising the center tread region A, respective intermediate regions B and respective shoulder tread regions C. Three types of tread rubber are used for the tread portion of the rear tire. JIS-A hardness of tread rubber of the intermediate tread region B is larger than JIS-A hardness of tread rubber of the center tread region A and JIS-A hardness of tread rubber of each shoulder tread region C.
