Tire Mounting
This information must be read and followed carefully
to prevent accidents and injuries during mounting.
Mounting a mismatched tire and wheel
will cause an explosion before it bead seats
during inflation. Attempts to force a bead
seat, by increasing air pressure, on mis-
matched tires and wheels will cause the
tire to violently explode, causing serious
personal injury or death to operator and/or
bystanders if standing over tire and wheel.
Check tire and wheel carefully before
mounting. Make sure the tire bead diameter
and wheel diameter match exactly. Consult
the tire manufacturer’s recommendations,
Tire Guide and/or Rubber Manufacturer's
Association for approved rim widths for
tire sizes.
Never mount a damaged tire. Never mount
a tire on a rusty or damaged wheel. Used
tires may have bead and/or tread damage.
Used rims may have flange damage where
the tire/rim was run down the road on a
flat tire. Run-flat tires are not meant to be
reused! Damaged tires and/or wheels may
explode.
CAUTION
When in doubt do not mount. Never mount
a tire and wheel handed to you by anyone
without checking both tire and wheel for
damage and to be certain the sizes match.
Used tires may have road hazard damage
or mount/demount damage, inspect care-
fully. Do not let untrained persons operate
tire changer and keep bystanders out of
service area.
CAUTION
Forcing the tire onto the rim can cause
bead damage. If you damage the tire bead
during mounting, STOP!, remove tire and
mark it as damaged. Do not mount a dam-
aged tire.
1.
Before any mounting, inspect tire for damage and
verify size match between tire and wheel (figure 20).
Figure 20 - Verify Size Match Between Tire and Wheel
2.
Inspect wheel closely for damage. Clean the
wheel and remove any light corrosion or rubber resi-
due (figure 21). Do not attempt to service a heavily
corroded wheel, damaged wheel, or bent wheel.
Figure 21 - Inspect and Clean the Wheel
3.
Inspect valve stem and replace if necessary. Next
lubricate tire beads liberally with tire manufacturer’s
approved rubber lubricant (figure 22).
