TIRE AND WHEEL RUNOUT

Radial runout is the difference between the high and low points on the tire or wheel.

Lateral runout is the wobble of the tire or wheel.

Lateral runout of more than 2.0 mm (.080 inch) measured near the shoulder of the tire may cause the vehicle to shake.

Radial runout of more than 1.5 mm (.060 inch) measured at the center line of the tread may cause the vehicle to shake.

Sometimes radial runout can be reduced. Relocate the wheel and tire assembly on the mounting studs (See Method 1). If this does not reduce runout to an acceptable level, the tire can be rotated on the wheel. (See Method 2).

METHOD 1 (RELOCATE WHEEL ON HUB)

METHOD 2 (RELOCATE TIRE ON WHEEL)

NOTE: Rotating the tire on wheel is particularly effective when there is runout in both tire and wheel.

• STEEL WHEELS: Radial runout 0.031 in., Lateral runout 0.031 in. (maximum)
• ALUMINUM WHEELS: Radial runout 0.02 in., Lateral runout 0.025 in. (maximum)
