How long does it take for car tires to cool off so I can check the air pressure?

Car tires typically take about 30 minutes to cool down after driving, but this can vary based on factors like the outside temperature and the length of your drive. It's best to check tire pressure when the tires are cold, ideally before driving or after a period of rest. Waiting for this cooling period ensures a more accurate pressure reading, as heat from driving can increase tire pressure.
