•Comfort and noise
•Ground clearance and parking at curbs
•Winter weather driving capability
•Wet weather driving capability
•All-Wheel driving capability (if applicable)
•Load leveling adjustment (if applicable)
When driving with the full-size dissimilar spare tire/wheel additional
caution should be given to:
•Towing a trailer
•Driving vehicles equipped with a camper body
•Driving vehicles with a load on the cargo rack
Drive cautiously when using a full-size dissimilar spare tire/wheel and
seek service as soon as possible.
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, jack handle and lug nut
wrenchRegular Cab: Behind the interior
trim on the passenger side of the
cab
SuperCrew and SuperCab: Under
the rear seat on the passenger side
The wing nut must be removed and the jack screw turned
counterclockwise to release pressure before the jack can be removed
from the holder.

Removing the spare tire
1. Use the ignition key to remove
the lock cylinder from the access
hole of the bumper to allow access
to the guide tube. Assemble the jack
handle as shown in the illustration.
2. Fully insert the jack handle
through the bumper hole and into
the guide tube through the access
hole in the rear bumper.
3. Turn the handle counterclockwise until tire is lowered to the ground,
the tire can be slid rearward and the cable is slightly slack.
4. Slide the retainer through the center of the wheel.
Tire change procedure
To help 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.

1. Park on a level surface, activate
hazard flashers and set the parking
brake.
2. Place gearshift lever in P (Park)
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.
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). 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.

•Front
Note:Use the frame rail as the jacking location point, NOT the control
arm.
•Rear
To lessen the risk of
personal injury, do not put
any part of your body under the
vehicle while changing a tire. Do
not start the engine when your
vehicle is on the jack. The jack is
only meant for changing the tire.
•Never use the front or rear
differential as a jacking point.
8. Remove the lug nuts with the lug wrench.
9. Replace the flat tire with the spare tire, making sure the valve stem is
facing outward. Reinstall the lug nuts until the wheel is snug against the
hub. Do not fully tighten the lug nuts until the wheel has been lowered.
10. Lower the wheel by turning the jack handle counterclockwise.

11. Remove the jack and fully
tighten the lug nuts in the order
shown (Refer toWheel lug nut
torque specificationslater in this
chapter for the proper lug nut
torque specification):
•Six lug nut wheel
•Seven lug nut wheel
12. Stow the flat tire. Refer toStowing the flat/spare tire.
13. Stow the jack and lug wrench. Make sure the jack is fastened so it
does not rattle when you drive.
14. Unblock the wheels.
Stowing the flat/spare tire
Note:Failure to follow spare tire stowage instructions may result in
failure of cable or loss of spare tire.
1. Lay the tire on the ground with the valve stem facing in the direction
specified on the Tire Changing Instructions located with the jack
hardware.
2. Slide the wheel partially under the vehicle and install the retainer
through the wheel center. Pull on the cable to align the components at
the end of the cable.
3. Turn the jack handle clockwise until the tire is raised to its stowed
position underneath the vehicle. The effort to turn the jack handle
increases significantly and the spare tire carrier ratchets or slips when
the tire is raised to the maximum tightness. Tighten to the best of your
ability, to the point where the ratchet/slip occurs, if possible. The spare
tire carrier will not allow you to overtighten. If the spare tire carrier
