Fuel Saving Tips

Hot tire pressure vs. cold tire pressure

Be aware that recommended tire air pressures are for a cold tire. If you have driven the car for a few miles or more, you need to add 4 PSI to each tire when checking pressure. The tire pressure will go down by itself as the tire cools and go back up by itself as the tire heats up again. Filling a warm or hot tire to the recommended cold tire pressure will be an under-inflated tire and reduce gas mileage.
