Tyre is one of the most essential part of vehicle as it plays a major part in ensuring safety of the vehicle, aerodynamics of a rotating tyre contributes about 33% of total vehicle drag. Also, generic trends connecting a vehicle’s shape to its aerodynamics are presented, followed by more specific race-car examples. Experimental studies have shown that the on-road turbulence affects the aerodynamics of vehicles significantly and that high turbulence intensities of up to 15% were seen in freeway traffic [Citation 10–12].
