Final answer:
A The wheel may fall off. The most likely result of under-torquing lug nuts is that the wheel may fall off.
Step-by-step explanation:
The most likely result of under-torquing lug nuts is that the wheel may fall off.
When lug nuts are not tightened properly, they can loosen over time. This can lead to the wheel becoming loose and eventually falling off while the vehicle is in motion. This is extremely dangerous and can result in a loss of control of the vehicle and potentially serious accidents.
To prevent this, it is important to follow the recommended torque specifications provided by the vehicle manufacturer when tightening lug nuts. Using a torque wrench ensures that the lug nuts are tightened to the correct torque, reducing the risk of them coming loose.
