If I remember correctly that was called "tire truing" or getting your tires "trued". Same principal as getting your rotors or drums cut. Did this with my first car, a 66 Impala. Had constant problems with vibration, that's when the alignment shop "trued" my tires, vibration eliminated. It did cost a few $$ though. The machine was kind of neat that did the job, as you watched some of your tire tread drop to the floor when shaved.....
