From the viewpoint of safety and product quality, it is important for a tire supplier to assure that the optimal equilibrium reached in the system vehicle/tires at the end of their development undergoes as few variations as possible during the mileage: hence it becomes of primary importance not only the performance itself, but also its 'robustness'. To verify the tire performances at different stage of life-cycle, physical prototypes have to be built and experimental wear tests, in both indoor and outdoor conditions, are required before getting the final assessments. In this context, the prediction by simulation of the tire wear evolution becomes a milestone to analyze the tire performances in its life-cycle, reducing the tire development time as well as its costs by a great amount, and matching the customers' needs of short development time and exigent performances targets. It's possible in this way to accelerate the development of new tire design concepts to control the robustness of tire performances. The purpose of this work is to summarize such a prediction technology. Steady-state FEM simulation is used here to study in a virtual environment the evolution of wear profile: simulation is based on tread outer material removal by adapting the tire tread mesh during the calculation.
