ROAD WHEEL AND TIRE ASSEMBLY
PFP:40300
Balancing Wheels (Bonding Weight Type)
NES000JP
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.
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 it 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.
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)
Þ
40 g (1.41 oz) bal-
ance weight (closer to calculated balance weight value)
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4
Þ
35 g (1.23 oz)
37.5
Þ
40 g (1.41 oz)
a.
Install balance weight in the position shown in the figure.
b.
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 tire
balance machine indication position (angle).
CAUTION:
●
Always use genuine NISSAN adhesion balance weights.
●
Balance weights are unreusable; 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 of 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 weights.
5.
Start tire balance machine. Make sure that inner and outer resid-
ual unbalance value are 7 g (0.25 oz) each or below.
●
If either residual unbalance value exceeds 7 g (0.25 oz), repeat installation procedures.
Rotation
NES000JQ
●
Follow the maintenance schedule for tire rotation service inter-
vals. Refer to
.
●
Do not include the spare tire when rotating tires.
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.
PEIA0033E
Maximum allowable unbalance
Dynamic (At rim flange)
Less than 7 g (0.25 oz) (one side)
Static (At rim flange)
Less than 14 g (0.49 oz)
Tightening torque of wheel nut

TRANSMITTER
A sensor-transmitter integrated with a valve is installed on a wheel,
and transmits a detected air pressure signal in the form of a radio
wave.

TIRE PRESSURE MONITORING SYSTEM
RECEIVER
The receiver receives the air pressure signal transmitted by the transmitter in each wheel.
LOW TIRE PRESSURE WARNING CONTROL UNIT
The low tire pressure warning control unit (1) reads the air pressure
signal received by the receiver, and controls the low tire pressure
warning lamp operations. It also has a judgementfunction to detect a
system malfunction.
LOW TIRE PRESSURE WARNING LAMP
The combination meter receives tire pressure status from the low tire
pressure warning control unit using CAN communication. When a
low tire pressure condition is sensed by the low tire pressure warn-
ing control unit, the combination meter low tire pressure warning
lamp is activated.
Low Tire Pressure Warning Lamp Indication
*: Standard air pressure is for 230 kpa (2.3 kg/cm
2
, 33 psi) vehicle.
