When the mercury drops, your tire pressure might, too.
Seasonal climatic changes result in air pressure losses on the order of 1 psi for every 10 degree F decrease in the ambient temperature, according to the National Highway Traffic Safety Administration.
Under-inflated tires decrease gas mileage and increase accidents, yet surveys show most drivers check inflation pressure far too infrequently. Only 1 in 4 drivers bother to check tire pressure even once a month.
Beyond proper inflation, making sure your tires are properly balanced, aligned and periodically rotated to ensure even wear and maximum life will help minimize their risk of failure.
