ALUMINUM WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel runout.
a. Remove tire from aluminum wheel and mount on a tire balance machine.
b. Set dial indicator as shown in the illustration.
c. If the total runout value exceeds the limit, replace aluminum wheel.
STEEL WHEEL (FOR EMERGENCY USE)
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheelrunout.
a. Remove tire from steel wheel and mount wheel on a tire balance machine.
b. Set two dial indicators as shown in the illustration.
c. Set each dial indicator to “0”.
d. Rotate wheel and check dial indicators at several points around the circumference of the wheel.
e. Calculate runout at each point as shown below.
f. 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 val ue is not available, use the
maximum value (negative or positive) for total runout.
g. If the total runout value exceeds the limit, replace steel wheel.
Lateral runout limit (A) : 0.3 mm (0.012 in)

ROAD WHEEL TIRE ASSEMBLY
ROAD WHEEL TIRE ASSEMBLY
Balancing Wheels (Bonding Weight Type)INFOID:0000000001327574
REMOVAL
Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:
 Be careful not to scratch th e road wheel during removal.
 After removing double-faced adhesive tape, wi pe 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 t hat should be used. Select the outer balance weight
with a value closest to the calculated value above and inst all 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.
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) ⇒ 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. Install balance weight in the position shown in the figure.
c. 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 non-reusable; always replace with new ones.
 Do not install more than three sheets of balance weight.
