removed from the tire and rim (figure 43).

Note: Mounting the top bead can be very difficult

Custom and Special
Wheels
Should a problem be encountered during
assembly or disassembly STOP! Avoid dam-
aging the other wheels. Continue assembly
only when problem is identified and cor-
rected.
Alloy Wheels: Some manufacturers offer wheels
with little or no drop center. These are not DOT
approved. The tire or wheel (or both) can be damaged
and the tire could explode under pressure, resulting in
serious injury or death. If you attempt to
mount/demount this type of wheel, use extreme cau-
tion (Figure 37).
European Performance Wheels (Asymmetrical
Hump): Some European wheels have very large
humps except near the valve hole. On these wheels,
the beads should be loosened near the valve hole on
both the upper and lower sides first (Figure 26 & 44).
