What must you be careful about, when putting on a wheel?

When putting on a wheel, it's essential to ensure that the wheel nuts are tightened correctly to ensure safety and prevent the wheel from coming loose while driving.

1. Tightening the wheel nuts with the prescribed torque is important because it ensures that the nuts are secured adequately without risking breakage or damage to the wheel. Proper torque specifications can typically be found in the vehicle's manual.

2. The alternative tightening method involves tightening the wheel nuts in a specific sequence rather than a circular pattern to ensure even pressure is applied across the wheel. This helps avoid warping or uneven wear that could lead to further issues.

Neglecting these steps, such as only checking the wheel nuts after driving a significant distance (like 500 km), increases the risk of a wheel coming loose while driving, which is a safety hazard. Thus, the combination of tightening the wheel nuts with the right torque and using the alternative tightening method is necessary for securing the wheels properly according to safety standards in German traffic regulations.
