ROAD WHEEL

PFP:40300

Inspection

NES00071

ALUMINUM WHEEL

Check tires for wear and improper inflation.

Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel
runout.

Remove tire from aluminum wheel and mount on a tire balance machine.

Set dial indicator as shown in the figure.

If the total runout value exceeds the limit, replace aluminum
wheel.

STEEL WHEEL (FOR EMERGENCY USE)

Check tires for wear and improper inflation.

Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel
runout.

Remove tire from steel wheel and mount wheel on a tire balance machine.

Set two dial indicators as shown in the figure.

Set each dial indicator to “0”.

Rotate wheel and check dial indicators at several points around
the circumference of the wheel.

Calculate runout at each point as shown below.

Select maximum positive runout value and the maximum nega-
tive value. Add the two values to determine total runout.

CAUTION:

In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.

If the total runout value exceeds the limit, replace steel wheel.

ROAD WHEEL TIRE ASSEMBLY

PFP:40300

Balancing Wheels (Bonding Weight Type)

NES00072

REMOVAL

Remove inner and outer balance weights from the road wheel.

CAUTION:

Be careful not to scratch the road wheel during removal.

Using releasing agent, remove double-faced adhesive tape from the road wheel.

CAUTION:

●

Be careful not to scratch the road wheel during removal.

●

After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.

WHEEL BALANCE ADJUSTMENT

●

If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for road wheels.

Set road wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.

When inner and outer unbalance values are shown on the wheel balancer indicator, multiply outer unbal-
ance value by 5/3 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.

CAUTION:

●

Never install the inner balance weight before installing the outer balance weight.

●

Before installing the balance weight, be sure to clean the
mating surface of the road wheel.

Indicated unbalance value

5/3 = balance weight to be installed

Calculation example:
23 g (0.81 oz)

5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance

weight (closer to calculated balance weight value)

NOTE:
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 = 35 g (1.23 oz)
37.5 = 40 g (1.41 oz)

ROAD WHEEL TIRE ASSEMBLY

WT-55

Install balance weight in the position shown in the figure.

When installing balance weight to road wheels, set it into the
grooved area on the inner wall of the road wheel as shown in the
figure so that the balance weight center is aligned with the wheel
balancer indication position (angle).

CAUTION:

●

Always use genuine Nissan adhesion balance weights.

●

Balance weights are non-reusable; always replace with
new ones.

●

Never install more than three sheets of balance weight.

If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other (as shown in
the figure).

CAUTION:

Never install one balance weight sheet on top of another.

Start wheel balancer again.

Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).

CAUTION:

Never install more than two balance weights.

Start wheel balancer. Make sure that inner and outer residual
unbalance values are 5 g (0.17 oz) each or below.

If either residual unbalance value exceeds 5 g (0.17 oz), repeat installation procedures.

Tire Rotation

NES00073

Follow the maintenance schedule for tire rotation service intervals. Refer to

MA-6, "Introduction of Peri-

odic Maintenance"

Do not include the spare tire when rotating the tires.

When installing the wheel, tighten wheel nuts to the specified
torque.

CAUTION:

●

When installing wheels, tighten them diagonally by divid-
ing the work two to three times in order to prevent the
wheels from developing any distortion.

●

Be careful not to tighten wheel nut at torque exceeding
the criteria for preventing strain of disc rotor.

Perform the ID registration, after tire rotation. Refer to

WT-24,

"ID Registration Procedure"
