14. Check Tire Pressure When Tires Are Cold for Accurate Readings
Most people check tire pressure after driving, when tires are warm and pressure reads higher. Always check when tires are “cold” — before driving or after sitting for at least three hours. Use the recommended PSI from the driver’s door jamb sticker, not the tire sidewall.
Proper cold inflation can improve fuel economy by 3%, extend tire life, and enhance handling and safety. Under-inflated tires cause blowouts and waste gas. Smart drivers keep a digital gauge in the glovebox and check monthly, noticing smoother rides and better mileage immediately.
