Troubleshooting guide

Abnormal tire wear patterns shown in the illustration can occur. Refer to the chart for the possible causes and actions.

Tire Wear Troubleshooting

Pattern	Possible cause	Action
(a)	Underinflation (both sides worn); Incorrect camber (one side worn); Hard cornering; Lack of rotation	Measure and adjust pressure; Repair or replace suspension parts; Reduce speed; Rotate tires
(b)	Overinflation; Lack of rotation	Measure and adjust pressure; Rotate tires
(c)	Incorrect toe-in	Adjust toe-in
(d)	Incorrect camber or caster; Malfunctioning suspension; Unbalanced wheel; Out-of-round brake drum or disc; Other mechanical conditions; Lack of rotation	Repair or replace suspension parts; Repair or replace; Balance or replace; Correct or replace; Correct or replace; Rotate tires

Inspection (continued)

4
Cracks, damage, and foreign matter (such as metal pieces, nails, and stones) in the tire and cracks, deformation, and damage to the wheel.
05U0QX-008
5
Loose wheel lug nut(s).
6
Air leaking from valve stem.

REMOVAL / INSTALLATION

Tighten the lug nuts to the specified torque in a crisscross fashion.

Specification	Value
lug nuts	≈863 - 1157N·m

lug nuts

863 - 1157N·m

CAUTION

The wheel-to-hub contact surfaces must be clean. Never apply oil to the nuts, bolts, or wheels, which cause looseness or seizure of the lug nuts.

TIRE ROTATION

To prolong tire life and assure uniform tire wear, rotate the tires every 6,000 km (3,750 miles), sooner if irregular wear develops.
