Abstract

PURPOSE:To prevent the separation of a main belt layer from tread rubber by disposing an auxiliary belt layer having a specific rate of diameter and density of cords smaller than those of main belt layer on the radial outside of main belt layer. CONSTITUTION:A tire 1 is provided with a carcass 7 having radially disposed carcass cords engaging the periphery of a pair of left and right bead cores 2 through both ends folded back and a main belt layer 10 having a plurality of main belt plies 10a, 10b disposed on the radial outside of carcass 7 and comprising main belt cords 11 using organic fiber and embedded in specific rubber. Then, a specific auxiliary belt layer 12 is disposed on the radial outside of main belt layer 10. The diameter all of auxiliary belt layer 12 is 20-30% of that d11 of main belt cord 11, while a sub-belt cord 13 having 35-65% of cord density is embedded in rubber having 60-85 degree of JISA hardness, and 27-45kg/cm<2> of 10% modulus.
