CUSTOM AND SPECIAL WHEELS
Alloy Wheels
Some manufacturers offer wheels with little or no
drop center. These are not DOT approved. The tire

could explode under pressure, resulting in serious in
jury or death. If you attempt to mount/demount this
type of wheel, use extreme caution.

beads should be loosened at the valve hole on both
the upper and lower sides first.

Corvette, BMW, Lamborghini Diablo) have a
