Wheel tether in Formula One refers to a strong cable securing each wheel to the chassis. It prevents detached wheels from flying in crashes. Regulations require tethers to withstand extreme forces. Engineers design tethers using high-strength materials. Drivers rely on them for safety during incidents. Example A car crashes into a barrier but the wheels remain attached due to wheel tethers. Tether performance is tested extensively before race use. Safety inspections ensure integrity before every event. Tethers therefore reduce injury risk to drivers and track personnel during accidents.
