KKCCDon asks: “I have a question about checking tire pressure. Is it best to do it when the tires are cold or hot? How much do I put in?”

Mike: Don, it is best to do it cold because as you drive the vehicle, the tires heat up, the air expands and it raises the pressure usually about 4 pounds PSI. Checking them warm will give you a false reading, so wait and do it cold. The recommended pressure is in your owners manual and also on a sticker on your drivers doorpost. By the way, correct tire pressures can greatly extend tire life and improve vehicle ride and handling.
