In this type of the tire, the inclination angle of cords in the belt gradually enlarges within a range of 7.degree.-20.degree. from the center of the crown region toward the tread side edge, and the tread is provided on each side edge portion with a substantially continuous rib having a width corresponding to 5-25% of the tread width.
