This project analyzes the aerodynamic and thermal performance of race car tyres made from Silicone Rubber (VMQ) using CFD simulations in SolidWorks. Four tread designsAero V Channel, Deep Flow Channel, Linear Groove, and Curved Flow Groovewere tested at speeds of 150 km/h and 200 km/h. According to the findings, tread geometry has a significant impact on the behavior of airflow, the distribution of pressure, and temperature stability. The Deep Flow Channel design achieved the best aerodynamic efficiency with uniform pressure and consistent temperature control at both speeds. Additionally, the Curved Flow Groove demonstrated reduced heat buildup and balanced airflow. In contrast, the Aero-V Channel and Linear Groove exhibited uneven pressure zones and higher thermal variations. Overall, optimized tread patterns improve drag reduction, cooling performance, and high-speed stability. These findings support the development of safer and more efficient high-performance tyres.
