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 is equipped with a spare tire that may be used as a spare or
a regular tire. The spare tire wheel may not match the road wheel, and is
not equipped with wheel trim. The wheel trim from the wheel/tire may
be used on the spare if the wheels match.
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.
Roadside Emergencies

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 Under the vehicle, just forward of
the rear bumper
Jack, lug nut wrench Regular cab: Under the seat on the
passenger side
Super Cab: Under the front or rear
seat on the passenger side
Super Crew cab: In the passenger
side rear storage compartment
Jack handle On top of the radiator support at
the front of the engine
compartment
Key, spare tire lock In the glove box
Removing the spare tire
1. If equipped with a two piece lug wrench, assemble the lug wrench as
shown in the illustration.
²To assemble, screw the parts
together. To disassemble,
unscrew.
2. Attach the spare tire lock key (A)
to the jack handle (B).
Roadside Emergencies
221

3. Insert the jack handle into the
rear bumper opening.
The handle will stop moving and
forward resistance to turning will be
felt when properly engaged.
4. Turn the handle counterclockwise
until tire is lowered to the ground,
the tire can be slid rearward and the
cable is slightly slack.
5. Remove the retainer from the spare tire.
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
jack handle ratchets when the tire is
raised to the stowed position. It will
not allow you to overtighten.
Tire change procedure
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.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
Refer to the instruction sheet (located with the jack) for detailed tire
change instructions.
Roadside Emergencies

hazard flashers and set the parking
brake.
2. Place gearshift lever in P (Park)
(automatic transmission) or in the
reverse gear (manual
transmission)and turn engine OFF.
3. Block the diagonally opposite
wheel.
4. Obtain the spare tire and jack
from their storage locations.
5. Use the tip of the lug wrench to
remove any wheel trim.
6. Loosen each wheel lug nut
one-half turn counterclockwise but
do not remove them until the wheel
is raised off the ground.
7. Position the jack according to the following guides and turn the jack
handle clockwise until the wheel is completely off the ground.
Roadside Emergencies
223

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) or in the reverse gear
(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,
someone could be seriously injured.
