Preventive Maintenance
WARNING! Improperly mounting and demounting
tire and rim assemblies is dangerous. Failure
to observe proper precautions could cause the
tire-rim assembly to burst explosively, causing
serious injury or death. See the wheel manufacturer's
literature for the proper way to mount and
demount your tires and rims. Follow their precautions
exactly.

Comparing Hub Piloted and Ball Seat Parts
WARNING! Do not mismatch wheel components.
Equipment that does not exactly match original
specifications or that is mismatched could
cause the wheels to break and separate from the
vehicle causing death or personal injury. Each
mounting system is engineered for use only with
its correct mating part. Be sure properly
matched components are used for each type of
mounting.
The following comparison (Table 8, ”Comparing Hubpiloted
and Ball-seat Wheels”), shows the difference
between parts used in hub pilot mount and ball seat mount
applications.
