What must be changed before driving with a heavy load?

When driving with a heavy load, it's crucial to adjust both the pre-tensioning of the springs and the tyre pressure. The pre-tensioning of the springs helps maintain vehicle stability and handling under a heavier load, ensuring that the suspension system can properly support the weight. This adjustment is necessary to prevent issues like bottoming out or excessive wear on the suspension components.

Tyre pressure is equally important; correct tyre pressure helps ensure that the tyres can handle the increased weight safely. Under-inflated tyres can lead to poor handling, increased stopping distances, and a higher risk of tyre blowouts.

German traffic regulations stress the importance of vehicle safety and maintenance, particularly when driving with heavier loads, to prevent accidents and ensure the vehicle operates reliably. Therefore, adjusting both the spring pre-tensioning and tyre pressure is vital for safe driving under these conditions.
