- Correct answer: Before driving, when the tires are cold.
Why this is the answer
The correct answer in the official bank: Before driving, when the tires are cold.
While driving, the tires heat up and the air inside them expands, so the pressure rises. The pressure the manufacturer recommends refers to cold tires, so check it before driving. Measuring hot tires gives a higher value. If you let air out because of it, the tires will be left underinflated. It is advisable to check regularly, and not only before the annual test.
