Abstract

PURPOSE: To ensure a motive performance on wet road and promote a remarkable reduction of tire rolling resistance, by applying a tread rubber layer having a characteristic of big value of loss tangent to around at least the designed groove of tire tread.
CONSTITUTION: A radial tire 1 is provided with a carcass layer 3 of toroid shape stopped circumferentially at an angle of 80W90° from one bead wire 2 to another bead wire 2. In this case, in the surface layer of a capped tread rubber layer 5 of the tire, is arranged a tread rubber layer A with a characteristic of value of loss tangent above 0.25 and below 0.50, and in the inner circumferential side given as the rest, is arranged a tread rubber layer B with a characteristic of value of loss tangent below 0.20, respectively. Each layer A, B is arranged for a quantity of the rubber B with a small loss factor of energy in the total region of capped tread, and a value of the effect to be more than 0.08 by the method of arrangement.
