What must be changed before driving with a heavy load?

When driving with a heavy load, it's essential to ensure that both the pre-tensioning of the springs and the tyre pressure are adjusted. Proper spring pre-tensioning helps maintain the vehicle's stability and handling characteristics under increased weight, which is crucial for safe driving. Correct tyre pressure is also vital, as it directly affects grip, fuel efficiency, and tyre wear.

In German traffic regulations, vehicle safety and operability are prioritized to prevent accidents, so both spring tension and tyre pressure adjustments are necessary when the load changes significantly. Not adjusting these components could lead to poor handling, increased stopping distances, and potentially hazardous driving conditions.
