PNEUMATIC TIRE MANUFACTURING METHOD AND PNEUMATIC TIRE

PROBLEM TO BE SOLVED: To allow a reinforcing belt to be arranged in a belt layer without deteriorating uniformity of a tire and durability of the belt.SOLUTION: A reinforcing belt 13 is arranged in a belt layer 10 and the belt cord 13a is coated with rubber. The reinforcing belt 13 is formed by being wound around with a reinforcing belt forming member 130 which has circumferential sides 131 and 132 parallel to a tire circumference direction and inclined sides 133 and 134 parallel to the belt cord 13a in an expanded state, so as to form a cylindrical shape in which when the belt cord 13a is wound around in a direction, in which the cord is inclined at cord angle θ3 relative to a tire circumference direction, a lower diameter D of the belt is equal to 940 mm or more and 960 mm or less, and a width W of the belt is equal to 270 mm or more and 310 mm or less, where the cord angle θ3, the lower diameter D of the belt and the width W of the belt have a relation of 0.57πD≤W/tanθ
