WHEEL AND TYRE -Troubleshooting31-4
WHEEL BALANCE ACCURACY
PURPOSE
This section contains tips and procedures for
achieving accurate wheel balance. Steering wheel
vibration and /or body shake can result if any of
these procedures are not carefully observed.
1. Wheels and tires must be properly mounted
on a balancer in order to achieve correct
balance. Centering the wheel on the shaft of
the balancer is essential for proper mounting.
2. Off-the-car wheel balancers must be calibrated
periodically to ensure good balancing results.
An inaccurately calibrated balancer could cause
unnecessary replacement of tires, shocks,
suspension components, or steering
components.Check your balancer’s calibration approximately
every 100 balances. Your wheel balancer’s
instruction manual should include calibration
procedures. If the calibration procedures
specifically for your balancer are missing, use the
generic steps in this section for zero calibration,
static balance, and dynamic balance checks. The
wheel balancer calibration checks are also
described in the flowchart. (Refer to P.31-5.)
PROCEDURE
Balancing Tips
1. Confirm that the balancer’s cone and the wheel
mounting cone are undamaged and free of
dirt and rust.
2. On this vehicle the wheel’s center hole on the
hub side has a chamfered edge. Use a
back-mounting cone on your wheel balancer
to center the wheel on the balancer shaft.3. Install a wheel mounting cone. The appropriate
size cone for this vehicle is 67.0 mm.
4. Before balancing the wheel, remove any wheel
weights from both sides. Also check both sides
for any damage.
5. When installing wheel weights, hammer them
at a straight (not diagonal) angle.

Confirming Proper Balance
1. After balancing the wheel, loosen the wing nut
and turn the wheel 180°against the balancer’s
hub. Then retighten the wing nut and check
the balance again. Repeat wheel balance if
necessary.2. Turn the wheel again 180°against the
balancer’s hub. If the wheel becomes
out-of-balance each time it is turned against
the balancer’s hub, the wheel balancer may
require calibration.
Wheel Balancer Calibration Checks
1. Mount an undamaged original-equipment alloy
rim and tire assembly (wheel) onto your
off-the-car wheel balancer. Balance the wheel.2.<>
Loosen the balancer wing nut, rotate the wheel
a half turn (180°), and retighten the nut.
Recheck the balance.

WHEEL AND TYRE -Troubleshooting31-5
DIf the imbalance is 5 g or less, the zero
calibration is OK. Rebalance the wheel, then
go to Step 4 to check static balance.
DIf the imbalance is more than 5 g, go to Step
3.
3. Loosen the balancer wing nut, rotate the wheel
1/4 turn (90°), and retighten the nut. Recheck
the wheel balance.
DIf the imbalance is 5 g or less, the wheel may
not be centered on the balancer, or the
balancing cones, the cup, and/or wing nut are
damaged, dirty, or inappropriate for the wheel.
You may need to refer to the balancer
manufacturer’s instructions to verify the correct
attachments. after making the necessary
corrections, recheck the wheel balance. If OK,
then go to Step 4.
DIf the imbalance is more than 5 g, the balancer
requires calibration. Contact the balancer
manufacturer for calibration by their repair
representative.
4.<>
Attach a 5-g weight to the outer rim. Recheck
the balancer. The balancer should detect 5±2
g of imbalance 170°to 190°away from both the
inner and outer 5-g weights.DIf the imbalance is within specification, the static
balance calibration is correct. Go to Step 5
to check the dynamic balance.
DIf the imbalance is out of specification, the
balancer requires calibration. Contact the
balancer manufacturer for calibration by their
repair representative.
5.<>
Attach a 5-g weight to the inner rim at 180°
opposite the 5-g weight that was added in step
4. Recheck the balance. The balancer should
detect 5±2g of imbalance 170°to 190°away
from both the inner and outer 5-g weights.
DIf the imbalance is within specification, the
dynamic balance calibration is correct. The
balancer calibration checks are complete.
DIf the imbalance is out of specification, the
balancer requires calibration. Contact the
balancer manufacturer for calibration by their
repair representative.

TYRE INFLATION PRESSURE CHECK
NOTE
For information on tyre inflation pressure, refer to the label
attached near the driver’s side door striker.
TYRE WEAR CHECK
Measure the tread depth of tyres.
Limit: 1.6 mm
If the remaining tread depth is less than the limit, replace
the tyre.
NOTE
When the tread depth of tyres is reduced to 1.6 mm or less,
wear indicators will appear.
WHEEL RUNOUT CHECK
Jack up the vehicle so that the wheels are clear of the floor.
While slowly turning the wheel, measure wheel runout with
a dial indicator.
Limit:
ItemSteel wheelAluminium wheel
Radial runout mm1.21.0
Lateral runout mm1.21.0
If wheel runout exceeds the limit, replace the wheel.
