spare tire JEEP GRAND CHEROKEE 2021 Owner handbook (in English)

Compact Spare Tire — If Equipped
The compact spare is for temporary emer-
gency use only. You can identify if your ve-
hicle is equipped with a compact spare by
looking at the spare tire description on the
Tire and Loading Information Placard located
on the driver’s side door opening or on the
sidewall of the tire. Compact spare tire de-
scriptions begin with the letter “T” or “S”
preceding the size designation. Example:
T145/80D18 103M.
T,S=Temporary Spare Tire
Since this tire has limited tread life, the
original equipment tire should be repaired (or
replaced) and reinstalled on your vehicle at
the first opportunity.
Do not install a wheel cover or attempt to
mount a conventional tire on the compact
spare wheel, since the wheel is designed
specifically for the compact spare tire. Do not
install more than one compact spare tire and
wheel on the vehicle at any given time.WARNING!
Compact and collapsible spares are for
temporary emergency use only. With these
spares, do not drive more than 50 mph
(80 km/h). Temporary use spares have lim-
ited tread life. When the tread is worn to
the tread wear indicators, the temporary
use spare tire needs to be replaced. Be
sure to follow the warnings, which apply to
your spare. Failure to do so could result in
spare tire failure and loss of vehicle con-
trol.
Collapsible Spare Tire — If Equipped
The collapsible spare is for temporary emer-
gency use only. You can identify if your ve-
hicle is equipped with a collapsible spare by
looking at the spare tire description on the
Tire and Loading Information Placard located
on the driver’s side door opening or on the
sidewall of the tire.
Collapsible spare tire description example:
165/80-17 101P.Since this tire has limited tread life, the
original equipment tire should be repaired (or
replaced) and reinstalled on your vehicle at
the first opportunity.
Inflate collapsible tire only after the wheel is
properly installed to the vehicle. Inflate the
collapsible tire using the electric air pump
before lowering the vehicle.
Do not install a wheel cover or attempt to
mount a conventional tire on the collapsible
spare wheel, since the wheel is designed
specifically for the collapsible spare tire.WARNING!
Compact and Collapsible spares are for
temporary emergency use only. With these
spares, do not drive more than 50 mph
(80 km/h). Temporary use spares have lim-
ited tread life. When the tread is worn to
the tread wear indicators, the temporary
use spare tire needs to be replaced. Be
sure to follow the warnings, which apply to
your spare. Failure to do so could result in
spare tire failure and loss of vehicle
control.

Full Size Spare — If Equipped
The full size spare is for temporary emer-
gency use only. This tire may look like the
originally equipped tire on the front or rear
axle of your vehicle, but it is not. This spare
tire may have limited tread life. When the
tread is worn to the tread wear indicators, the
temporary use full size spare tire needs to be
replaced. Since it is not the same as your
original equipment tire, replace (or repair)
the original equipment tire and reinstall on
the vehicle at the first opportunity.
Limited Use Spare — If Equipped
The limited use spare tire is for temporary
emergency use only. This tire is identified by
a label located on the limited use spare
wheel. This label contains the driving limita-
tions for this spare. This tire may look like the
original equipped tire on the front or rear axle
of your vehicle, but it is not. Installation of
this limited use spare tire affects vehicle
handling. Since it is not the same as your
original equipment tire, replace (or repair)
the original equipment tire and reinstall on
the vehicle at the first opportunity.
WARNING!
Limited use spares are for emergency use
only. Installation of this limited use spare
tire affects vehicle handling. With this tire,
do not drive more than the speed listed on
the limited use spare wheel. Keep inflated
to the cold tire inflation pressures listed on
your Tire and Loading Information Placard
located on the driver’s side B-Pillar or the
rear edge of the driver’s side door. Replace
(or repair) the original equipment tire at
the first opportunity and reinstall it on your
vehicle. Failure to do so could result in
loss of vehicle control.
Wheel And Wheel Trim Care
All wheels and wheel trim, especially alumi-
num and chrome plated wheels, should be
cleaned regularly using mild (neutral Ph)
soap and water to maintain their luster and to
prevent corrosion. Wash wheels with the
same soap solution recommended for the
body of the vehicle and remember to always
wash when the surfaces are not hot to the
touch.Your wheels are susceptible to deterioration
caused by salt, sodium chloride, magnesium
chloride, calcium chloride, etc., and other
road chemicals used to melt ice or control
dust on dirt roads. Use a soft cloth or sponge
and mild soap to wipe away promptly. Do not
use harsh chemicals or a stiff brush. They
can damage the wheel’s protective coating
that helps keep them from corroding and
tarnishing.
CAUTION!
Avoid products or automatic car washes
that use acidic solutions or strong alkaline
additives or harsh brushes. Many aftermar-
ket wheel cleaners and automatic car
washes may damage the wheel's protective
finish. Such damage is not covered by the
New Vehicle Limited Warranty. Only car
wash soap is recommended.
When cleaning extremely dirty wheels includ-
ing excessive brake dust, care must be taken
in the selection of tire and wheel cleaning

CAUTION!
• Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns
and large bumps, especially with a
loaded vehicle.
• Do not drive for a prolonged period on
dry pavement.
• Observe the traction device manufactur-
er’s instructions on the method of instal-
lation, operating speed, and conditions
for use. Always use the suggested oper-
ating speed of the device manufacturer’s
if it is less than 30 mph (48 km/h).
• Do not use traction devices on a com-
pact spare tire.
Tire Chains (Traction Devices) — SRT
Use of traction devices require sufficient tire-
to-body clearance. Follow these recommen-
dations to guard against damage.
• Traction device must be of proper size for
the tire, as recommended by the traction
device manufacturer.• Install on Rear Tires Only
• Due to limited clearance, RUD-GRIP
4X4 or Equivalent is recommended on
295/45ZR20 tires.
WARNING!
Using tires of different size and type
(M+S, Snow) between front and rear axles
can cause unpredictable handling. You
could lose control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
• Because of restricted traction device
clearance between tires and other sus-
pension components, it is important
that only traction devices in good condi-
tion are used. Broken devices can cause
serious damage. Stop the vehicle imme-
diately if noise occurs that could indi-
cate device breakage. Remove the dam-
aged parts of the device before further
use.
CAUTION!
• Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns
and large bumps, especially with a
loaded vehicle.
• Do not drive for a prolonged period on
dry pavement.
• Observe the traction device manufactur-
er’s instructions on the method of instal-
lation, operating speed, and conditions
for use. Always use the suggested oper-
ating speed of the device manufacturer’s
if it is less than 30 mph (48 km/h).
• Do not use traction devices on a com-
pact spare tire.
Tire Rotation Recommendations
The tires on the front and rear of your vehicle
operate at different loads and perform differ-
ent steering, handling, and braking func-
tions. For these reasons, they wear at unequal
rates.
