ABSTRACT:
A radial ply pneumatic tire, characterized by uniform tread wear and improved traction is disclosed. The tire includes a radial ply carcass, first and second sidewalls overlying the lateral portions of the carcass, a tread overlying the crown region of the carcass, a breaker positioned between the tread and the crown region of the carcass, and a cushion positioned between the breaker and the tread. The cushion is constituted by a rubber mixture which is softer than the rubber mixture constituting the tread and it extends symmetrically about the median equatorial plane of the tire, thereby providing a more pliable support in the central portion of the tread than in the shoulder region thereof. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
