machine.

b.

Set dial indicator as shown in the illustration. Refer to 

WT-40,

"Road Wheel"

.

INFOID:0000000001675576

WHEEL BALANCE REMOVAL

1.

Remove wheel and tire using power tool.

2.

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

CAUTION:

• Be careful not to scratch the wheel during removal.
• After removing double-faced adhesive tape, wipe clean traces of releasing agent from the wheel.

WHEEL BALANCE INSTALLATION AND 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 wheels.

1.

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

2.

When inner and outer imbalance values are shown on the wheel balancer indicator, multiply outer imbal-
ance value by 1.6 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value and install it to the designated outer position of, or at the desig-
nated 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 wheel.
Indicated imbalance 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 that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 g = 35 g (1.23 oz)
37.5 g = 40 g (1.41 oz)

WHEEL AND TIRE ASSEMBLY

a.

Install balance weight in the position shown.

b.

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

CAUTION:

• Always use Genuine NISSAN adhesion balance weights.
• Balance weights are not reusable; always replace with

new ones.

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

c.

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

CAUTION:

Do not install one balance weight sheet on top of another.

3.

Start wheel balancer again.

4.

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

CAUTION:

Do not install more than two balance weights.

5.

Start wheel balancer. Make sure that inner and outer residual
imbalance values are 5 g (0.18 oz) each or below.
• If either residual imbalance value exceeds 5 g (0.18 oz),

repeat installation procedures.

Rotation

INFOID:0000000001675577

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

MA-39, "Tire Rotation"

.

1.

Remove wheels and tires.

2.

Rotate wheels and tires on each side from front to back as
shown. Do not include the spare wheel and tire when rotating
the wheels and tires.

CAUTION:

When installing wheels and tires, tighten them diagonally
by dividing the work two to three times in order to prevent
the wheels from developing any distortion.

3.

Adjust the tire pressure to specification. Refer to 

WT-40, "Tire"

.

Transmitter (Pressure Sensor)

INFOID:0000000001675572

REMOVAL

1.

Remove wheel and tire using power tool.

2.

Deflate tire. Unscrew transmitter retaining nut and allow transmitter to fall into tire.

3.

Gently bounce tire so that transmitter falls to bottom of tire.
Place wheel and tire assembly on tire changing machine and
break both tire beads. Ensure that the transmitter remains at the
bottom of the tire while breaking the bead.

4.

Turn tire so that valve hole is at bottom, and gently bounce the
tire to ensure transmitter is near valve hole. Carefully lift tire onto
turntable and position valve hole (and transmitter) 270 degrees
from mounting/dismounting head.

5.

Lubricate tire well, and remove top side of tire. Reach inside the
tire and remove the transmitter.

6.

Remove the second side of the tire as normal.

INSTALLATION

1.

Place first side of tire onto rim.

2.

Apply suitable silicone lubricant to new transmitter seal then install seal on transmitter. Refer to 

MA-10,

"Fluids and Lubricants"

.

NOTE:
Always replace the seal after every disassembly.
