摘要： The invention improves tire flat spotting by providing a bead assembly that has bead filler elements disposed outside the body cords so that the turn up portion of the ply of body cords is disposed immediately back against the main portion of the ply of body cords above the bead core. This carcass structure increases the stiffness of the lower sidewall and decreases the flat spotting experience by the tire. In one embodiment of the invention, a reinforcing ply is wrapped around the bead filler elements to further increases the stiffness of the lower sidewall. In another embodiment, a bead filler element is disposed inside the body cords so that an air pocket is not formed in the carcass during the manufacturing process.

摘要： A method for designing pneumatic tires for rolling conditions employs a finite element tire model configured by an operator. A first set of variables is applied to the tire model and steady state footprint conditions resulting from such application of the variables to the tire model are compared against predetermined footprint constraints to determine if the steady state footprint conditions and the footprint constraints have converged. If they have not, the set of control variables is incremented and the comparison is undertaken again until the steady state footprint conditions in the footprint constraints have converged. The concept of the invention is presented with particular application to a determination of the abrasion energy dissipation or wear potential, cornering stiffness, and residual aligning torque.
