Radial runout of more than 1.5 mm (.060 inch) measured at the center line of the tread may cause Lateral runout of more than 2.0 mm (.080 inch) measured near the shoulder of the tire may cause the Sometimes radial runout can be reduced. Relocate the wheel and tire assembly on the mounting studs METHOD 1 (RELOCATE WHEEL ON HUB) (1) Drive vehicle a short distance to eliminate tire flat spotting from a parked position. (2) Check wheel bearings and adjust if adjustable or replace if necessary. (3) Check the wheel mounting surface. over from the original position. (5) Tighten wheel nuts until all are properly torqued, to eliminate brake distortion. (6) Check radial runout. If still excessive, mark tire sidewall, wheel, and stud at point of maximum METHOD 2 (RELOCATE TIRE ON WHEEL) NOTE: Rotating the tire on wheel is particularly (1) Remove tire from wheel and mount wheel on service dynamic balance machine. (2) Check wheel radial runout (Fig. 2) and lateral runout (Fig. 3). • STEEL WHEELS: Radial runout 0.031 in., Lat- eral runout 0.031 in. (maximum) • ALUMINUM WHEELS: Radial runout 0.020 in., Lateral runout 0.025 in. (maximum) (3) If point of greatest wheel lateral runout is near original chalk mark, remount tire 180 degrees. STANDARD PROCEDURE STANDARD PROCEDURE - MATCH MOUNTING Wheels and tires are match mounted at the factory. This means that the high spot of the tire is matched Fig. 2 Radial Runout 1 - MOUNTING CONE Fig. 3 Lateral Runout 1 - MOUNTING CONE 22 - 2 TIRES/WHEELS VA |
