WHEELS AND TIRES
Irregular Tire Wear
Abnormal tire wear patterns, such as shown in the illustration, may occur. Refer to the chart for the possible
causes and remedies.
Wear condition
SHOULDER WEAR Possible cause l Underinflation (both sides worn) l Hard cornering l Lack of rotation Remedy
l Measure and adjust pressure l Reduce speed l Rotate tires
CENTER WEAR
l Overinflation l Lack of rotation *Measure and adjust pressure l Rotate tires
FEATHERED EDGE
l Incorrect toe adjustment l Adjust toe-in
UNEVEN WEAR
l Incorrect camber or caster l Malfunctioning suspension l Unbalanced wheel
*Out-of-round brake drum or disc
l Lack of rotation *Repair or replace axle or suspension parts
l Repair or replace suspension l Balance or replace
*Correct or replace
l Rotate tires

WEIGHT
REMOVAL / INSTALLATION
1. The wheel-to-hub contact surfaces must be clean.
2. Tighten the lug nuts to the specified torque.
Tightening torque:
88-l 18 N-m (9-12 m-kg, 85-87 ft-lb)
Caution
l When reinstalling a wheel, retighten the lug nuts to
the specified torque after about 1,000 km (820 miles)
driving.
TIRE ROTATION
To prolong tire life and assure uniform tire wear, rotate the tires
from every 3,000 km (1,860 miles) to every 6,000 km (3,720
miles).
Caution
l Do not include “TEMPORARY USE ONLY” spare tire
in rotation.
l Use the best tires on the front axle.
l After rotating the tires, adjust each tire to the speci-
fied air pressure. (Refer to page Q-3.)
WHEEL BALANCE ADJUSTMENT
If a wheel becomes unbalanced or if a tire is replaced or
repaired, the wheel must be rebalanced to within specification.
Maximum unbalance (at rim edge)
13 inch wheel: 11 g (0.39 oz)
14 inch wheel: 10 g (0.35 or)
Caution
l Do not use more than two balance weights on the
inner or outer side of the wheel.
l If the total weight exceeds 1OOg (3.5 oz) perslde,
rebalance after moving the tire around on the rim.
l Attach the balance weights tightly on the wheel.
l Select suitable balance weights for steel or alumi-
num alloy wheels.
l Do not use an on-car balancer on automatic trans-
axle models; it may cause transaxle damage.
