What must you take into consideration when checking tyre pressure?

You answered correctly by selecting both "Load/Number of passengers in the car" and "Tyre temperature." The tyre pressure should be adjusted based on how much load your vehicle is carrying; a heavier load often requires higher tyre pressure for safety and optimal handling. Tyre temperature is also important because pressure can increase as tyres get warm during driving, so you should check and adjust tyre pressure when the tyres are cold for an accurate reading. The material of the wheels does not affect the tyre pressure requirements, so it is not relevant to this question. Knowing these factors will help you maintain proper tyre pressure for safety and efficiency.
