- Michelin used to develop new tires through extensive testing of physical prototypes, which was costly and time-consuming - In 2011, Michelin started using CAE software to simulate tire designs to reduce the number of prototypes needed for testing - The CAE software allows for quicker evaluation of design objectives like durability and aquaplaning performance, reducing development time and costs - However, uncertainties in road conditions and other factors mean the simulation results may vary from real-world performance, so the software cannot fully replace physical testing
