Shape optimization of complex engineering structures involves an implicit objective function and implicit constraint conditions; therefore, analytical sensitivity expressions are difficult to derive. Finite element analyses of tires are characterized by multiple nonlinearities which make the tire shape optimization more complex. A self-adaptive scheme based on the response surface method was developed to optimize tire tread shapes. This ray step approach uses incremental ray step formulas to treat violations of the constraint conditions, with special treatments to suppress oscillations. The objection function for the optimization problem is based on the uniformity of the contact force with the tread shape parameters as the design variables. Converged results requesting less than twenty iterations verify the feasibility and efficiency of the approach for complex optimization problems.
