TREAD FOR RECYCLED TIRE, AND RECYCLED TIRE

摘要

PROBLEM TO BE SOLVED: To provide a tread for a recycled tire having durability improved by improving low a heating property as in a new tire and increasing the adhesiveness of a base tire to tread rubber, and to provide a recycled tire. SOLUTION: This tread is formed in a double layer structure having a cap rubber layer and a base rubber layer formed of different types of rubber compositions. The rubber thickness of the base rubber layer is 20 to 40% of the total rubber thickness of the tread. The loss tangent (tanδC) of the rubber composition of the cap rubber layer and the loss tangent (tanδB) of the rubber composition of the base rubber layer are in the relation of tanδC>tanδB. The base rubber layer is formed of a rubber composition having a loss tangent (tanδB) of 0.12 or less measured at 23°C. COPYRIGHT: (C)2004,JPO&NCIPI
