CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Spare tire information
Your vehicle may be equipped with a spare tire that can be used as
either a spare or a regular tire. The spare tire is not equipped with wheel
trim. The wheel trim from the original wheel/tire may be used on the
spare.
If your vehicle is equipped with 4WD, a spare tire of a different
size than the road tires should not be used. Such a tire could
result in damage to driveline components and make the vehicle
difficult to control.
Location of the spare tire and tools
The spare tire and tools for your vehicle are stowed in the following
locations:
Tool Location
Spare tire
(pick-up trucks only)Under the vehicle, just forward of the rear
bumper
Jack Regular cab, crew cab and SuperCab
without rear bench seat: Fastened to floor
pan behind rearmost seat on passenger side
SuperCab with rear bench seat: Under rear
bench on passenger side
Jack handle and lug
wrenchOn top of the radiator support at the front
of the engine compartment
Key, spare tire lock
(if equipped)In the glove box
Removing the spare tire (with spare tire carrier only)
1. The following tools are required to remove the spare tire:
•one handle extension and one
typical extension. To assemble,
align button with hole and slide
parts together. To disconnect,
depress button and pull apart.

•one wheel nut wrench. Slide over
square end of jack handle.
2. If equipped, unlock and remove the spare tire lock from the rear
bumper drive tube using the the spare tire lock key and the jack handle.
3. Insert the hooked end of the jack
handle into the rear bumper drive
tube.
The handle will stop moving and
you will feel forward resistance to
turning when properly engaged.
4. Turn the handle counterclockwise
and lower the spare until you can
slide the tire rearward and the cable
is slack.
5. Remove the retainer through the center of the wheel.

Stowing the spare tire
1. Lay the tire on the ground with the valve stem facing up.
2. Slide the wheel under the vehicle
and install the retainer through the
wheel center.
3. Turn the jack handle clockwise
until the tire is raised to its original
position underneath the vehicle. The
effort to turn the jack handle
increases significantly and the spare
tire carrier ratchets when the tire is
raised to the stowed position. The spare tire carrier has a built-in ratchet
feature that will not allow you to overtighten.
4. Check that the tire lies flat to the frame assembly. Push against the
tire to make sure it is tightly seated under the vehicle. Loosen or
retighten if necessary.
5. If removed, install the spare tire lock into the bumper drive tube with
the spare tire lock key and jack handle.
Tire change procedure
1. Park on a level surface, activate
hazard flashers and set the parking
brake.
•Automatic transmission: Place
gearshift lever in P (Park).
•Manual transmission: Place
gearshift lever in R (Reverse).
•Electronic Shift On the Fly four
wheel drive: Place transfer case
in 2WD, 4x4 HIGH or 4x4 LOW.
•Manual shift transfer case four
wheel drive: Place transfer case
in 2H, 4H or 4L.

To prevent the vehicle from
moving when you change a
tire, be sure the parking brake is
set, then block (in both
directions) the wheel that is
diagonally opposite (other side
and end of the vehicle) to the tire
being changed.
2. Turn engine OFF and block the diagonally opposite wheel (block not
provided).
3. Remove the jack, jack handle, lug wrench and spare tire from the
stowage locations.
4. Use the tip of the lug wrench to remove any wheel trim.
5. Loosen each wheel lug nut
one-half turn counterclockwise but
do not remove them until the wheel
is raised off the ground.
When one of the rear wheels is off the ground, the transmission
alone will not prevent the vehicle from moving or slipping off the
jack, even if the transmission is in P (Park) (automatic transmission)
or R (Reverse) (manual transmission). To prevent the vehicle from
moving when you change the tire, be sure that the parking brake is set
and the diagonally opposite wheel is blocked.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
