PURPOSE: To prevent or suppress the failure of the rim dislocation of a tire.

CONSTITUTION: In a tire provided with an integrated chafer consisting of the oriented rubber, the chafer rubber is oriented so that the ratio (C=B/A) of the 300% tensile modulus (B) in the circumferential direction of the tire to the 300% tensile modulus (A) in the width direction of the tire of the rubber chafer is in the range of 1<C≤1.5 at the rim/flange attachment/detachment part, and the ratio (D=A/B) of the 300% tensile modulus (A) in the width direction of the tire to the 300% tensile modulus (B) in the circumferential direction of the tire of the rubber chafer is in the range of 1<D≤1.5 at the part below the bead core.
