Aerodynamic Impact of Tire Shapes differences on Electric Vehicles

As the automotive industry increasingly shifts toward electrification, minimizing vehicle drag becomes essential to enhance autonomy range and meet consumer expectations. Additionally, recent European regulation (WLTP) requires car manufacturers to provide reliable emissions values for all the vehicles configurations, hence emphasizing the relevance of achieving accurate drag results. One of the largest contributors to the overall drag of the vehicle are the tires. This presentation leverages PowerFLOW’s simulations capabilities to explore how tire shape differences can have relevant effect on aerodynamics and force coefficients, particularly with clean underbody designs like in electric vehicles.
