How is the wheel speed of a car calculated?

[DelGriffin]

Methods for calculating car wheel speed: Wheel speed equals the vehicle's driving speed divided by the tire circumference. The rotational speed of the tire is related to many factors, such as gear ratio, tire diameter, etc. Different types of tires produce different rotational speeds. When the number of wheel rotations is constant, the wheel diameter is directly proportional to the distance traveled. Car tires are one of the important components of a vehicle, directly contacting the road surface and working with the car suspension to mitigate impacts during driving, ensuring good ride comfort and smooth driving performance. They also ensure excellent adhesion between the wheels and the road surface, improve the vehicle's traction, braking, and off-road capabilities, and bear the weight of the car.
