WHEELS (BONDING WEIGHT TYPE)

WHEELS (BONDING WEIGHT TYPE) : Adjustment

INFOID:0000000001766472

BARANCING WHEELS (BONDING WEIGHT TYPE)

Preparation Before Adjustment

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

CAUTION:

• Be careful not 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.

1.

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

2.

When inner and outer unbalance values are shown on the tire balance machine indicator, multiply outer
unbalance 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 in to the designated outer position of, or at
the designated angle in relation to the road wheel.

CAUTION:

• Do not 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.

installed
Calculation example:
23 g (0.81 oz) 

×

 5/3 = 38.33 g (1.35 oz) 

 37.5 g (1.32 oz) bal-

ance weight (closer to calculated balance weight value)
NOTE:
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
36.2 

 35 g (1.23 oz)

36.3 

 37.5 g (1.32 oz)

b.

Installed balance weight in the position.
• When installing balance weight (1) to road wheels, set it into

the grooved area (A) on the inner wall of the road wheel as
shown in the figure so that the balance weight center (B) is
aligned with the tire balance machine indication position
(angle)(C).

CAUTION:

• Always use genuine NISSAN adhesion balance weights.
• Balance weights are non-reusable; always replace with

new ones.

• Do not install more than three sheets of balance weight.

c.

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:

Do not install one balance weight sheet on top another.

3.

Start tire balance machine again.

4.

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

CAUTION:

Do not install more than two balance weight.

5.

Start tire balance machine. Make sure that inner and outer resid-
ual unbalance values are 5 g (0.17 oz) each or below.

6.

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

CHASSIS MAINTENANCE

• Follow the maintenance schedule for tire rotation service intervals.

Refer to 

MA-6, "Schedule 1"

.

• When installing the wheel, tighten wheel nuts to the specified

torque.

CAUTION:

• Do not include the T-type spare tire when rotating the tires.
• When installing wheels, tighten them diagonally by dividing

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.

• Use NISSAN genuine wheel nuts for aluminum wheels.

• Perform the ID registration, after tire rotation. Refer to 

WT-5, "ID REGISTRATION PROCEDURE : Special

Repair Requirement"

.

TIRE ROTATION (for 19 inch wheel models)

• Tire cannot be rotated in vehicle, as front tire are different size from rear tire and the direction of wheel rota-

tion is fixed in each tire.

CAUTION:

• Do not include the T-type spare tire when rotating the tires.
• Use NISSAN genuine wheel nuts for aluminum wheels.

Safety Device Preventing from Being Incorrectly installed

FRONT BRAKE DISC ROTOR AND FRONT WHEEL

• Front and rear wheel size for this model differs, therefore special pin (1) has been installed on the front brake

disc rotor (2). To accommodate this pin a hole (3) has been provided on the front wheel (4) (the rear wheel
does not have this hole.) and in some case the rear wheel is being mistakenly installed on the front.
