A runout gauge includes a stand (such as a tripod), and a gauge bar pivotally mounted on the stand. The gauge bar includes a wheel on its upper end positioned above the pivot for rollingly engaging an outer surface of a vehicle tire, and further includes a pointer located a greater second distance below the pivot. By this arrangement, movement of the wheel on the tire due to runout causes the pointer to move along an amplified path having a length greater than the movement of the wheel, thus making it easier to read. The illustrated stand includes indicia for measuring movement of the pointer, and also includes gauge slides on a frame component that abut the pointer in a manner showing an extent of the pointer's movement, which relates to the runout on the tire. |
