Chevrolet Equinox Service Manual: Tire and Wheel Assembly Runout Measurement - On-Vehicle
Raise and support the vehicle.Closely inspect each tire for proper and even beadseating.If any of the tire beads were not properly or evenly seated,reseat the tire bead, then proceed to step-4. Refer toTire and Wheel Removal and Installation.
Wrap the circumference of each tire with tape-(1)in the center tread area.
Wrapping the tread with tape allows for a smooth and accuratereading of radial runout to be obtained.
Position the dial indicator on the taped portion of the tiretread such that the dial indicator is perpendicular to the tiretread surface.Slowly rotate the tire and wheel assembly one completerevolution in order to find the low spot.Set the dial indicator to zero at the low spot.Slowly rotate the tire and wheel assembly one more completerevolution and measure the total amount of radial runout.Specification
Maximum tire and wheel assembly radial runout –measured on-vehicle: 1.52-mm(0.060-in)
Position the dial indicator on a smooth portion of the tiresidewall, as close to the tread as possible, such that the dialindicator is perpendicular to the tire sidewall surface.Slowly rotate the tire and wheel assembly one completerevolution in order to find the low spot. Ignore any jumps or dipsdue to sidewall splices.Set the dial indicator to zero at the low spot.Slowly rotate the tire and wheel assembly one more completerevolution and measure the total amount of lateral runout. Ignoreany jumps or dips due to sidewall splices and attain an averagerunout measurement.
Specification
Maximum tire and wheel assembly lateral runout –measured on-vehicle: 1.52-mm(0.060-in)Repeat steps 4-through-12 until all ofthe tire and wheel assembly radial and lateral runout measurementshave been taken.Lower the vehicle.
