Fuel Saving Tips
Winter is bad for tire pressure
Remember that tire pressure goes down between 1/2 and 1 lb for every 10 degree drop in outside air tempurature. So for us here in the north, we lost 50 degrees in less than a week, so those tires could be down 5 pounds even if you just topped them off. Also low tires are terrible in snow.
