LIGHT SPOT
Figure 6-31: Marking Wheel and Tire Assembly Light
NOTE: If more than 15 oz. of weight is required to balance the
tire, wheel and runflat (if installed) assembly, rotate tire 180°
on wheel. Tires on steel two piece wheels can be balanced us-
ing either adhesive backed tape-on or clip-on type balance
weights. All aluminum wheel and tire assemblies require the
use of tape-on weights only. Do not use wheel balancing liq-
uids to balance wheel and tire assembly. Balancing liquids may
be incompatible with and cause damage to wheel, tire, runflat,
and CTIS components.
NOTE: There is very little clearance between geared hubs and
the inside diameter of the wheels. When installing tape-on bal-
ance weights on the inside diameter of the wheel, position the
weights to afford adequate clearance to the geared hubs.
5. Attach balance weights to inner and/or outer edges of
wheel (indicated by dynamic balancer), ensuring weight is
centered on light spot, or weights are placed evenly to
sides of light spot if more than one weight is used. When
installing weight clips, use a small hammer or clip-
clawhammer tool. Tap weights to conform to wheel flange
edge contour (Figure 6-32).
6. Start balance cycle and repeat steps 3 through 5 until tire is
properly balanced.
7. Remove wheel and tire assembly from dynamic balancer
and install on vehicle.
