Here are a few reasons why a gearbox failure might cause a tire to come off:
* Loss of power: If the transmission fails, the engine will no longer be able to send power to the wheels. This can cause the vehicle to lose control, and the tire can come off.
* Broken driveshaft: If the driveshaft (the shaft that transmits power from the transmission to the wheels) fails, the wheels will no longer be able to turn. This can cause the tire to come off.
* Differential failure: The differential is a component of the transmission that allows the wheels to turn at different speeds. If the differential fails, the wheels will no longer be able to turn independently, and the tire can come off.
Gearbox failure can be a dangerous problem. A tire coming off can cause a vehicle to lose control and crash, resulting in serious injury or even death. If you experience any of the symptoms of a gearbox failure, such as grinding noises or difficulty shifting gears, you should have your transmission inspected immediately.
