What must you take into consideration when checking tyre pressure?

When checking tyre pressure, it is important to consider the load or number of passengers in the car because more weight increases the pressure needed for safe driving and proper tyre performance. Additionally, tyre temperature matters because tyre pressure rises as the tyres heat up during driving; therefore, tyre pressure should ideally be measured when the tyres are cold to get an accurate reading. The material of the wheels (steel or aluminium) does not affect the required tyre pressure. Understanding these factors helps ensure safe handling, fuel efficiency, and tyre longevity.
