Did you know that this extreme cold we’ve been experiencing for the last couple of weeks can drastically alter your tire pressure? You may have noticed your TPMS light go on periodically. If this is the case, your tires are probably underinflated even if it turns off after driving awhile. According to the U.S. Tire Manufacturers Association, for every 10 degree drop in temperature, tire pressure decreases one to two pounds per square inch. Ideally you should check your tire pressure in all 5 tires (yes, including the spare) once a month, but with weather this cold it should be checked even more regularly.
The correct tire pressure for your vehicle is NOT the pressure listed on the tires themselves. The number on the tire sidewall is a maximum pressure rating for those tires. The correct pressure depends the car. The proper tire pressure for your vehicle is listed on a sticker inside the driver’s door jamb or can be found in your owner’s manual. Perform your checks when your vehicle has been sitting for several hours.
Underinflated tires cause greater friction with the road surface and cannot bear as much of a weight load, increasing your chance of a blowout. It will also wear out your tires faster and can reduce your gas mileage by 10-15%. Overinflated tires reduce your contact with the road, decreasing traction and increasing the likelihood of rollover.
The importance of properly maintaining your tires CANNOT be overemphasized. Remember tires are the only contact between your vehicle and the road.
