With a good spin balance machine it will also give you a "rating" on your overall tire "quailty". All tires are NOT created equal. BEFORE balancing I have the tire\wheel combo checked, often the tire has to be relocated on the rim. Sometimes a tire is so "far out" of specs (weight) it can only be balanced with a LOT of weight. The "numbers" are somewhat standard. Jaguar will not accept new tires from a manufacturer that fall out of their "specs", for instance. Ford, I suspect, will run "what ever". If you need a LOT of weight, whats wrong with this picture?
