What is the diameter of a 20-inch wheel in centimeters?

[VonAlessandra]

20-inch wheel diameter is 50.8 centimeters, with one inch equaling 2.54 centimeters. Tires are circular elastic rubber products mounted on various vehicles or machinery that roll on the ground. They are one of the essential components of a car and the only part that comes into contact with the road. Some car owners only replace the tires on the drive wheels when changing tires. For example, some front-wheel-drive car owners only replace the two front tires, while some rear-wheel-drive car owners only replace the two rear tires. The main functions of tires include: supporting the entire weight of the vehicle and bearing the load of the car; transmitting traction and braking torque to ensure adhesion between the wheels and the road; reducing and absorbing vibrations and impacts during driving; preventing severe vibrations and premature damage to automotive components; adapting to the high-speed performance of the vehicle and reducing driving noise; ensuring driving safety, handling stability, comfort, and fuel efficiency.
