As temperatures drop, you may notice the tire pressure warning light appearing on your dashboard more often.
This is a common issue during colder months and is a result of basic science.
Understanding why this happens and what to do about it can keep you safer on the road this winter.
Air contracts as it gets colder, meaning the air molecules inside your tires take up less space. For every 10°F drop in temperature, tire pressure decreases by about 1-2 PSI (pounds per square inch).
Tips for maintaining tire pressure in cold weather:
Check Regularly : Use a reliable tire pressure gauge to check your tires at least once a month, especially after a significant temperature drop.
Follow Recommendations : Check your vehicle's manual or the label on the driver’s side door for the recommended PSI.
Inspect Before Driving : Check pressure when your tires are cold—before driving or after sitting for at least three hours.
Invest in a Portable Pump : Having a portable air compressor handy can save you a trip to the gas station when your tires need a quick top-off.
