General Description
The spare tire is located under the rear end of non EMP
vehicles. For exact locations refer to the 2006 LSSV

The hoist shaft allows a link between the tire hoist and
the rear bumper. The factory spare tire hoist tools are
used to remove the spare. An access hole in the rear of
the bumper is provided to allow access. If the tire hoist
is damaged it must be replaced.

different locations depending on vehicle content. The

• In vehicle, behind the passenger front seat
• In the front right corner of the cargo area
• On the rear bumper on a swing away mount
Tires Description
The beadlock system can only be used on multiple-
piece wheels. This device fits securely between the tire
beads and positively locks the tire to the wheel rim
flange. Beadlocks allow vehicle operations at the low
tire air pressure conditions required for better mobility in
mud, sand and snow. By reducing the air pressure, the
tire footprint is increased significantly, thus allowing a
greater area of traction or contact. The beadlock also
performs as a safety device to insure that the tire does
not “unseat” from the rim or rotate on the wheel at
these low air pressure settings, while also preventing
the entry of foreign objects, debris or water into the
tire’s air chamber. It is used in conjunction with the tire
pressure monitoring system.
The replacement tire for the beadlock rim is a MTR
285/75 R16 Goodyear.
