“Winter weather can require extra attention and quick response when driving, and the cold temperatures can also impact tire care,” said Bill Geaman, Cooper’s Manager of Consumer Relations. “Outside temperatures can impact tire pressure by one pound per square inch (psi) for every 10-degree drop in temperature. Because even a small drop in tire pressure may alter a vehicle’s safety, it is very important to pay extra attention to your tire pressure during extreme temperatures.”
To check tire pressure, find the car’s ideal air pressure listed on the sticker inside the car door, glove box, fuel door or in the car’s manual. Remove the tire’s valve cap and press a tire gauge firmly onto the valve stem. The end of the tire pressure gauge will pop up and show the psi reading of the tire. If this number matches the recommended tire pressure, it’s good to go. If the number is lower than the recommended tire pressure, the tire is underinflated. If the reading on the gauge is higher than the pressure recommended for the car, some air needs to be released.
