Document Type and Number:
Japanese Patent JP3053020
Kind Code:
B2
Abstract:
The present invention provides an optimum radial tyre which is suitable for each car. In the present invention, an alpha value is introduced as indicating the properties of the car and the tread rubber of the tyre is selected according to the alpha value. Accordingly, the present invention provides a radial tyre which comprises a tread and sidewall, wherein the tread has the claimed relation between a viscoelasticity (tan delta ) peak temperature (Tg) and an alpha value which indicates the properties of a car, and a one side half width (W/2) near the tan delta peak temperature of 25 deg or less.
