    Patent number: 4041647
    Abstract: A method and apparatus for improving tire uniformity with respect to radial force variation and free radial run-out is disclosed. The method comprises continuously rotating the tire about its own rotational axis under a constant normal load, measuring the variation in the forces generated in the radial direction around the circumference of the tire tread, grinding either or both tread shoulders to correct excessive variation in the radial forces, measuring the variation in the free radial run-out of the tire tread around the circumference along both shoulders and the centers thereof, and grinding either or both shoulders and/or the center of said tire tread to correct excessive variation in the free radial run-out of the tire.
    Type: Grant
