TC3500 Operation Instructions 3. Advanced Procedures • 33
Continue mounting by rotating the wheel counterclockwise until upper bead is
mounted.
Retract upper roller and swing bead roller assembly away to prepare for inflation.
HINT: Use of bead depressor (without inserting tail) may assist in
locking tire to rim during mounting.
3.5 Mounting 20-Inch and Larger Automotive Wheels and Tires
Twenty-inch and larger wheels have recently been introduced into the market. The
handling of these tires on the TC3500 will not pose any difficulties. Bead loosening
and demounting follow the same general procedures as the normal low profile tires.
During mounting, the mounting head sitting on the rim edge prevents the upper roller
from reaching its mounting position on the sidewall of the tire. This can be resolved
easily and without any modification by positioning the roller first and then the
mounting head. This solution works for all 20-inch combination wheels.
3.6 Matching/Optimizing of Tire to Rim
Matching/Optimizing allows positioning of the rim to the tire for proper mounting to
minimize vibrations. This procedure must be done with both beads fully loosened and
well lubricated.
Match/Optimize the rim to the tire as follows:
Set the rim diameter approximately 1 to 2 inches larger than the actual rim
diameter.
Bring the lower bead roller up until it contacts the tire.
Bring the upper bead roller down until it contacts the tire.
Rotate wheel counterclockwise and continue rotating for next three steps.
Lock upper roller and push in on sidewall of the tire until upper bead is in drop
center of rim.
Lock lower roller and push in on sidewall of the tire until rim and tire are rotating
at two different speeds.
NOTE: For reverse drop center rims, reverse the previous two
procedures:
Lock lower roller and push in on sidewall of tire until
bead is in drop center.
Lock upper roller and push in on sidewall of tire until rim
and tire are rotating at two different speeds.
