You have to remove a defective tyre. In what sequence should you proceed?

The correct sequence for removing a defective tyre is crucial for safety and effectiveness. According to German traffic rules, the first step is to secure the vehicle against rolling away by engaging the parking brake and placing wheel chocks if necessary. This prevents accidents while you're working.

Next, you position the car jack appropriately to avoid damage and ensure stability. After that, the wheel nuts should be loosened while the vehicle is still on the ground. This is important because it reduces the risk of the wheel spinning when you try to unscrew the nuts. Only after loosening the nuts should you jack up the vehicle to a safe height. Finally, you can completely remove the loosened wheel nuts and take off the wheel.

Following this correct sequence minimizes the risk of injury and ensures compliance with safety regulations, as mandated in the German road safety guidelines.
