ABSTRACT:
A pneumatic tire the aspect ratio of which is not more than 50% has, for reinforcing a tread portion, a belt comprising at least two rubber coated cord layers having cords arranged obliquely at angles with respect to an equatorial plane of the tire of 26.degree. or more, and a belt reinforcing layer arranged outside the belt and comprising at least one organic fiber cord layer having cords arranged substantially parallel with respect to the equatorial plane of the tire. The tire is molded in a mold with a cross-sectional profile of a molded surface facing the tread portion having a radius smaller than that of a nominal tire cross-sectional profile by 1% or more of a section width of the tire and forming a convex curve to a cavity.
