Tire Tread contact area re-surfacing 'car wash'

Tire treads wear down very slowly over time as the surface of the road scrubs off particles of rubber. My idea would be to build a system very similar to driving your car through a car wash. As the car is pulled along through the system, various steps are accomplished along the way. Step one might be to spin the tires and sand, wire brush or scrub them. Step two might be for the tire to roll over a heated surface to get them up to a certain temperature. Step three may be to roll the tires over a rubber glue, perhaps a two part system composed of the glue, then a catalyst. (The two part system would be necessary so that the glue cures only on the tires and not gum up the equipment). These steps are preparing the tire for the next step, which is the application of a new contact surface. This is accomplished by the tire rolling over a layer of finely ground powdered rubber, which would adhere to the tire, building up to an optimal engineered thickness. Another trip over a heated surface to quickly cure the rubber, and a new rubber surface has been applied to the contact surfaces of the tire, extending the life of the tires by 'X' amount of miles. The car would simply enter at one end and come out the other with a new thin coat of rubber applied to the tires. To accomodate application specific tire compounds, you could have different "car washes" applying different blends of rubber. (EG. One for regular passenger tires, one for trucks, one for performance tires etc.). The customer would be instructed to bring his vehicle back for another coating at pre- determined, thousand miles intervals, just as you do now for scheduled oil changes. Tires would need to pass certain criteria before being allowed to have this service performed. IE they would need to have a minimum amount of tread remaining, even tread-wear, not over a certain age based on the DOT number on the tire etc. The "raw" material for this system would come from of course, old tires, of which we seem to have an un-ending supply.
