DEFINITION

Classification: 152/559

Reinforcing cords run in opposite directions in successive carcass ply, i.e., bias plies:

(under subclass 558) Subject matter wherein the carcass reinforcing materials in the carcass plies are so disposed that the reinforcing cords in adjacent carcass plies subtend each other such that they are in a superimposed angular relationship relative to one another.

(1) Note. Generally in order for a carcass structure to be considered biased, the angular orientation of the reinforcing elements with respect to the mid-circumferential plane of the tire is greater than about 15 deg. and more generally greater than about 30 deg. and less than about 60 deg..
