What must you remember with regard to tyre pressure?

Your answer is correct. According to German traffic rules, it is important to check tyre pressure regularly, including the spare wheel, to ensure safe driving and avoid tyre damage. Additionally, when the vehicle is heavily loaded, you should increase the tyre pressure to the level specified in the vehicle manual to maintain proper handling and prevent excessive tyre wear. Reducing tyre pressure before long trips is incorrect and can be dangerous because it reduces stability and increases the risk of tyre failure. Maintaining the correct tyre pressure as recommended helps ensure safety, fuel efficiency, and tyre longevity.
