Abstract
Abstract A tire construction is disclosed wherein there is a combination of radial and bias plies, there typically being twice as many bias plies as radial plies. In a preferred embodiment for passenger car utilization, three plies are employed, a radial ply being disposed outside two bias plies. Both the bias and radial plies are preferably 12s X 12z twist for 1,260/2 and 840/3 denier cords and 10S X 10Z twist for 1,100/2 and 840/2 denier cords, while either of these twists may be employed with 1,100/3 denier cords. The angle of the bias ply in the cured crown is preferably 35* and the radial ply preferably 90*. The preferred thermal shrinkage at 190* C. of both plies is approximately 17 percent (12 tpi). With these specific parameters, a cooperative structure between the radial and bias plies is effectuated which facilitates manufacture of these tires especially with respect to conventional radial ply tires.
