Based on the tyre designation, when should you check the road-worthiness of your tyres?

The correct way to ensure the road-worthiness of your tyres involves checking them at several key times.

1. Every time you take possession of a third-party vehicle is important because you need to ensure the tyres are safe and suitable for driving, as you might not know their maintenance history.
2. With every tyre change is crucial as it ensures that the new tyres are properly installed, correctly inflated, and also checks the condition of the wheel rims and brakes.

These practices align with German traffic regulations, which emphasize safety and the responsibility of drivers to ensure that their vehicles, including all components, are in good working order before taking to the road. Regular checks help prevent accidents and maintain vehicle performance, which is essential under the Straßenverkehrs-Zulassungs-Ordnung (Road Traffic Licensing Regulations).
