Tire Wear
1. Check the remaining tread.
Remaining tread
Standard tires: 1.6mm (0.063 in) min.
Snow tires: 50% of tread ’ _,I’
2. The tire should be replaced if the wear indicators are
exposed.
Inspection (Tire and Wheel)
The wheel or tire should be replaced if any crack, damage,
deformation or other problem is found.
Wheel and Tire Runout
1. Jack up the vehicle and place it on safety stands.
2. Set the probe of a dial indicator against the wheel, and meas-
ure the runout through one full revolution.
Runout:
_..’
Horizontal Aluminum wheel: 2.0 (0.079), Steel wheel: 2.5 (0.098)
Vertical 1.5 (0.059)
3. Replace the wheel if necessary.
Caution
l Adjust wheel balance after replacement of a wheel
or tire.
Lug Nut
1. Verify that the lug nuts are tightened to the specified torque.
Tightening torque:
66-l 16 N*m (9-12 m-kg, 65-67 ft-lb)

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.

PRE-INSPECTION
1. Check the tire inflations and set to the recommended pressure, if necessary.
2. Inspect the front wheel bearing play; replace the bearing if necessary.
3. inspect the wheel and tire runout.
4. Inspect the ball joints and steering linkage for any excessive looseness.
5. The vehicle must be on level ground and have no luggage or passenger load.
6. The difference in height between the left and right sides from the center of the wheel to the fender brim
must not exceed
10mm (0.39 in).
7. Shake the vehicle to check operation of the shock absorbers.

1. Loosen the left and right tie rod locknuts, then turn the tie
rods equally.
Caution
l The left and right tie rods are both right threaded,
so, to increase the toe-in, turn the right tie rod to-
ward the front of the vehicle and the left tie rod
equally toward the rear.
l One turn of the tie rod (both sides) changes the toe-
in by about 6mm (0.24 in).
