Abstract
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.
