Before beginning your journey, what do you have to check in connection with the tyres?

You are correct to check for any damage and loss of pressure before starting your journey. According to German traffic rules, it is essential to ensure that the tyres are in good condition and properly inflated to prevent accidents and ensure safe driving. However, checking the tread depth is not part of the immediate pre-journey checks, although it is important for overall tyre maintenance. The legal minimum tread depth in Germany is 1.6 mm, not 1 mm, so the choice about 1 mm tread depth is incorrect. Focusing on damage and pressure before driving helps avoid sudden tyre failures while on the road.
