Tire Chains
{WARNING
If the vehicle has dual wheels
or P265/65R18, P275/55R20,
LT265/70R17, LT265/70R18,
LT265/60R20, P285/50R20,
P285/45R22 or 285/45R22 size
tires, do not use tire chains.
They can damage the vehicle
because there is not enough
clearance. Tire chains used on
a vehicle without the proper
amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by the
tire chains could cause you to
lose control of the vehicle and
you or others may be injured in
a crash.(Continued)
WARNING (Continued)
Use another type of traction
device only if its manufacturer
recommends it for use on the
vehicle and tire size combination
and road conditions. Follow
that manufacturer's instructions.
To help avoid damage to the
vehicle, drive slowly, readjust,
or remove the device if it is
contacting the vehicle, and do
not spin the vehicle's wheels.
If you do find traction devices that
will fit, install them on the rear
tires. Notice:
If the vehicle does not
have dual wheels and has a
tire size other than P265/65R18,
P275/55R20, LT265/70R17, LT265/
70R18, LT265/60R20, P285/50R20,
P285/45R22, or 285/45R22, use
tire chains only where legal and
only when you must. Use chains
that are the proper size for the
tires. Install them on the tires
of the rear axle. Do not use
chains on the tires of the front
axle. Tighten them as tightly as
possible with the ends securely
fastened. Drive slowly and
follow the chain manufacturer's
instructions. If you can hear the
chains contacting the vehicle,
stop and retighten them. If the
contact continues, slow down
until it stops. Driving too fast or
spinning the wheels with chains
on will damage the vehicle.

Full-Size Spare Tire
Your vehicle, when new, had a
fully-inflated spare tire. A spare
tire may lose air over time, so
check its inflation pressure regularly.
SeeTire Pressure on page 10‑66
and Vehicle Load Limits on
page 9‑25 for information regarding
proper tire inflation and loading your
vehicle. For instruction on how to
remove, install or store a spare tire,
see “Removing the Flat Tire and
Installing the Spare” and“Storing a
Flat or Spare Tire and Tools” under
Tire Changing on page 10‑86. Notice:
If the vehicle has
four-wheel drive and the different
size spare tire is installed on the
vehicle, do not drive in four-wheel
drive until you can have your
flat tire repaired and/or replaced.
You could damage the vehicle,
and the repair costs would not
be covered by your warranty.
Never use four-wheel drive when
the different size spare tire is
installed on the vehicle.
Your vehicle may have a different
size spare tire than the road tires
originally installed on your vehicle.
This spare tire was developed for
use on your vehicle, so it is all right
to drive on it. If your vehicle has
four-wheel drive and the different
size spare tire is installed, keep
the vehicle in two-wheel drive. After installing the spare tire on your
vehicle, you should stop as soon as
possible and make sure the spare
tire is correctly inflated. Have the
damaged or flat road tire repaired
or replaced as soon as you can
and installed back onto your vehicle.
This way, the spare tire will be
available in case you need it again.
Do not mix tires and wheels of
different sizes, because they will
not fit. Keep your spare tire and its
wheel together. If your vehicle has
a spare tire that does not match
your vehicle's original road tires
and wheels in size and type, do not
include the spare in the tire rotation.
