This is National Tire Safety Week, and as Benjamin Franklin said "an ounce of prevention is worth a pound of the cure." Joe Greiner owns Greiner Discount Tires in Washington. He says it's important to keep an eye on air pressure, and tread condition. Greiner says during hot weather, it's important to check tire pressure when the tires are cool, not after driving around all day. He also says keeping tires in proper working order can also save money, because under-inflated tires cut down fuel efficiency.
