ABSTRACT A tire uniformity machine to process rubber pneumatic tires by sensing their force variations while they are rotating and then grinding rubber therefrom in selected amounts and regions corresponding to the sensed force variations. The machine processes such tires more rapidly than previous machines, and includes mechanical means to rotate the tire at a speed higher than the industry standard of 60 revolutions per minute and rotate the tire at a lower speed to selectively grind rubber therefrom. A sensor is provided to detect force variations in the tire while rotating at the higher speed and, in response thereto, to produce frequency modified electrical signals corresponding to the detected force variations at a frequency higher than the industry standard of 60 cycles per minute. Rubber removal means are also provided for selectively removing rubber from the rotating tire at the lower speed. A summer amplifier is provided to receive and filter the produced signals from the sensor and to forward such filtered signals to a microprocessor which interprets such filtered signals, stores such interpreted signals, and activates the mechanical means and the rubber removal means in a programmed manner in accordance with such stored signals.
