Abstract
A tire having a modified geodesic belt is described. The ideal geodesic belt path is modified to select the centerline belt angle and to avoid excessive build up of the belt at the belt edges. The method includes the step of calculating the minimum three dimensional distance from one belt edge to the other belt edge preferably using dynamic successive approximation.
Claims17
A pneumatic tire having a carcass and a belt reinforcing structure, the belt reinforcing structure comprising:
- A first belt layer having cords arranged at an angle of 5 degrees or less with respect to the midcircumferential plane, and a modified geodesic belt reinforcing structure, the modified geodesic belt structure formed in a three dimensional minimum path extending in alternation to turnaround points at each lateral edge, wherein the modified geodesic belt reinforcing structure is wider than the first belt layer and is located radially outward of the first belt layer.
