ROAD WHEEL
PERIODIC MAINTENANCE
ROAD WHEEL
Inspection
INFOID:0000000010380607
APPEARANCE
Road Wheel
• Check road wheel for deformation, cracks, corrosion and other damage.
• Check wheel nuts for looseness by using torque wrench.
Tire
• Check entire circumference and both sides of each tire for deformation, cracks, scratch and other damage.
• Check tire tread for wear and foreign matter such as nails and small rock.
• Check that tire pressure is the specified value.
Wheel Balance Adjustment (Aluminum Wheel)
INFOID:0000000010380608
PREPARATION BEFORE ADJUSTMENT
Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:
• Never scratch the road wheel during removal.
• After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
ADJUSTMENT
• The details of the adjustment procedure are different for each model of wheel balancer. Therefore, refer to
each instruction manual.
• 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 aluminum 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 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, always to clean the mating surface of the road wheel.
a.
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) 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:
37.4
⇒
35 g (1.23 oz)
37.5
⇒
40 g (1.41 oz)

• 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 balance weights.
• Balance weights are non-reusable; always replace with
new ones.
• Never install three or more 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:
Never install one balance weight sheet on top of another.
3.
Start the 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:
Never install three or more balance weight.
5.
Start the tire balance machine. Check that the inner and outer residual unbalance value is within the
allowable unbalance value.
CAUTION:
If either residual unbalance value exceeds limit, repeat installation procedures.
Wheel Balance Adjustment (Steel Wheel)
INFOID:0000000010380609
PREPARATION BEFORE ADJUSTMENT
Remove balance weight from the road wheel.
CAUTION:
Never scratch the road wheel during removal.

ROAD WHEEL
• The details of the adjustment procedure are different for each model of wheel balancer. Therefore, refer to
each instruction manual.
• 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 steel wheels.
1.
Set road wheel to wheel balancer, and then start wheel balancer.
2.
Install balance weight to road wheel according to the unbalance and position (angle) displayed on wheel
balancer.
CAUTION:
• Always use genuine NISSAN balance weights.
• Balance weights are non-reusable; always replace with new ones.
• Always use a plastic hammer when attaching the weight.
• Never install three or more balance weights on one side.
3.
Start the tire balance machine. Check that the inner and outer residual unbalance value is within the
allowable unbalance value.
CAUTION:
If either residual unbalance value exceeds limit, repeat installation procedures.
Tire Rotation
INFOID:0000000010380610
• Follow the maintenance schedule for tire rotation service intervals.
• When installing the wheel, tighten wheel nuts to the specified
.
CAUTION:
• Never 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.
• Never tighten wheel nut at torque exceeding the criteria.
• Use NISSAN genuine wheel nut.

the limit, replace aluminum wheel.
How to Handle Puncture Repair Agent (With Puncture Repair Kit)
INFOID:0000000010494017
CAUTION:
• Never spill the sealant in the tire during repair.
• If the sealant spills, wipe it out with a waste cloth.

ROAD WHEEL TIRE ASSEMBLY
• Never reuse the repair kit hose used for a temporary repair of a flat tire because some of the punc-
ture repair agent remains in the hose.
• After using a puncture repair agent, replace air valve with a new one.
1.
Remove tires from the vehicle.
2.
Remove tire from road wheel, using a tire changer.
CAUTION:
• When deflating a tire, cover the valve with a waste cloth to prevent the sealant from splattering.
• Never spill the sealant in the tire during repair.
3.
Dispose of sealant in the removed tire.
CAUTION:
• Wipe out sealant spilled on the road wheel, tire, tire changer, and floor with a waste cloth.
• Drained sealant or expired sealant returned by the customer must be disposed according to the
law and local regulations.
• Fix a tire blowout, if repairable.
NOTE:
Sealant blocks holes caused by blowouts. These holes may not be found and repaired, depending on
the level of blowout. Therefore, it is necessary to check tire air pressure frequently and replace tire with
a new one, if the air pressure is decreasing.
• Replace tire with a new one, if not repairable.
CAUTION:
Never dispose of tires with the sealant contained.
