K-Line Industries has introduced what it calls a "simple-to-use, economical" tire runout gauge that measures both radial and lateral tire runout conditions. Use of this tool can help eliminate irregular tire wear and ride vibration extending tire life, the company says.
 
The patented gauge uses a roller wheel placed against the tire tread combined with a gauge bar, individual low- and high-spot sliders, and magnified measurement readout that quickly shows the amount of runout present. If the runout exceeds stated limits, a check can be made and repairs completed for faults such as bent or cocked rims, improperly adjusted wheel bearings, improper tire bead seating, tire flat spots, improperly tightened rim clamps and rear rim spacers.

The K-Line gauge can pinpoint problems either directly related to the tire and rim or some other trouble area. It’s an early indicator of wheels and/or tires that need to be reworked or discarded.
