NOTE:
If the bottle jack will not lower by turning the dial (thumb-
wheel) by hand, it may be necessary to use the jack driver in
order to lower the jack.
4. By rotating the lug wrench clockwise, raise the vehicle until the wheel just clears the surface.
5. Remove the lug nuts and pull the wheel off. On single rear-wheel (SRW) trucks, install the spare wheel and lug
nuts with the cone shaped end of the wheel nuts toward
the wheel. On 3500 dual rear-wheel models (DRW)
trucks, if the outer tire is being replaced then leave the
inner wheel on the vehicle. If the inner wheel is being replaced remove the outer wheel and replace the inner
wheel. The wheel nuts are a two-piece assembly with a
flat face. Lightly tighten the lug nuts. To avoid the risk of
forcing the vehicle off the jack, do not fully tighten the lug
nuts until the vehicle has been lowered.
Rear Inner Wheel Proper Placement (Dual Rear Wheel Equipped)
CAUTION!
Before raising the wheel off the ground, make sure that
the jack will not damage surrounding truck parts and
adjust the jack position as required.
WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.6

the sidewall preceding the size designation. Example:
P215/65R15 95H.
• European — Metric tire sizing is based on European design standards. Tires designed to this standard have the
tire size molded into the sidewall beginning with the
section width. The letter "P" is absent from this tire size
designation. Example: 215/65R15 96H. • LT (Light Truck) — Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric tires
is the same as for P-Metric tires except for the letters “LT”
that are molded into the sidewall preceding the size desig -
nation. Example: LT235/85R16.

• Temporary spare tires are designed for temporary emergency use only. Temporary high pressure compact spare tires have
