On-Car Tire Grinder for Improved Ride Smoothness 720465

“Smooth road shake” complaints resulting from tire and wheel nonuniformities have been greatly reduced on original equipment tires. However, the problem still exists on after-market tires that have not been ground.
The On-Car Tire Grinder (OCG) was developed by General Motors Research to provide a means for correcting smooth road shake complaints in the field. The device effectively duplicates the grinding done on original equipment tires. It has a low initial cost, does not require removing the tire from the car, and has proved practical for service use.
Several companies have been given a free license to manufacture the On-Car Grinder for sale to tire stores and automobile dealers.
