What must you take into consideration when checking tyre pressure?

When checking tyre pressure, it's essential to consider both the load or number of passengers in the car and the tyre temperature. The load affects how much air is needed in the tyres to ensure they can support the weight of the vehicle adequately. Under-inflated tyres can affect handling and increase wear.

The tyre temperature is also crucial because tyres expand when they heat up. If you check the pressure when the tyres are cold, you get a more accurate reading of the pressure you should maintain. If you only consider the material of the wheels, you might miss the vital factors that directly impact the safety and performance of the vehicle.

According to German traffic regulations, proper tyre maintenance, including maintaining the correct tyre pressure, is crucial for optimal vehicle operation and safety on the road. Neglecting these factors can lead to unsafe driving conditions.
