Why should you measure tire pressure when the tires are cold?
- Driving lowers the air pressure inside the tires
- Driving warms the tires and raises the pressure inside

Show answer
Correct answer: Driving warms the tires and raises the pressure inside
The manufacturer's recommended pressure reflects a cold tire, and driving makes the pressure increase, so you measure cold or compensate.
