Question 7997
The tires are at the correct pressure. After a trip, you find that the pressure has increased. What should you do?
- Pour water on the tires to cool them down.
- Do not let air out, because the air has heated up and that is why the pressure is higher.
- Let air out of the tires.
Show answer and explanation
Correct answer: Do not let air out, because the air has heated up and that is why the pressure is higher.
Don't let any air out. As you drive, the tire heats up, the air inside expands, and the pressure rises. When it cools down, the pressure will return to its previous level. Putting water on the tires doesn't help either. To find the actual pressure, measure it when the tires are cold.
