What must you take into consideration when checking tyre pressure?

When checking tyre pressure, it's crucial to consider both the load or number of passengers in the car and the tyre temperature.

The load affects how much pressure is needed; more weight typically requires higher pressure to ensure safety and optimal performance. The tyre temperature is also important because tyre pressure changes with temperature–it increases when tyres are warm due to driving and decreases when they are cold.

Failing to consider these factors can lead to underinflation or overinflation, affecting traction, handling, and fuel efficiency, which can be a violation of safety regulations as outlined in the German road traffic laws. Properly inflated tyres are essential for safe driving and vehicle efficiency.
