What happens when you let the air out of hot tires?

When you let the air out of hot tires, the pressure inside the tire decreases, which can lead to a temporary increase in tire volume as the air cools. This can cause the tire to become under-inflated, leading to reduced handling, increased wear, and a higher risk of tire damage or blowouts. Additionally, if the tires are still warm from driving, the pressure drop can result in uneven wear patterns or decreased performance. It's generally recommended to check and adjust tire pressure when they are cold for accurate readings.
