2018 JEEP GRAND CHEROKEE steering

WARNING!
• Always drive with each tire inflated to
the recommended cold tire inflation
pressure.
Both under-inflation and over-inflation affect
the stability of the vehicle and can produce a
feeling of sluggish response or over respon-
siveness in the steering.
NOTE:
• Unequal tire pressures from side to side
may cause erratic and unpredictable steer-
ing response.
• Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consump-
tion.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and reduced
tread life, resulting in the need for earlier tire
replacement.Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfort-
able ride. Over-inflation produces a jarring
and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is
listed on the left side B-Pillar or rear edge of
the passenger door.
At least once a month:
• Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgement when determining
proper inflation. Tires may look properly
inflated even when they are under-inflated.
• Inspect tires for signs of tire wear or visible
damage.
CAUTION!
After inspecting or adjusting the tire pres-
sure, always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the valve stem.Inflation pressures specified on the placard
are always “cold tire inflation pressure”. Cold
tire inflation pressure is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than
1 mile (1.6 km) after sitting for a minimum of
three hours. The cold tire inflation pressure
must not exceed the maximum inflation pres-
sure molded into the tire sidewall.
Check tire pressures more often if subject to
a wide range of outdoor temperatures, as tire
pressures vary with temperature changes.
Tire pressures change by approximately 1 psi
(7 kPa) per 12°F (7°C) of air temperature
change. Keep this in mind when checking
tire pressure inside a garage, especially in the
Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature = 32°F
(0°C) then the cold tire inflation pressure
should be increased by 3 psi (21 kPa), which
equals 1 psi (7 kPa) for every 12°F (7°C) for
this outside temperature condition.

Replacement Tires
The tires on your new vehicle provide a bal-
ance of many characteristics. They should be
inspected regularly for wear and correct cold
tire inflation pressures. The manufacturer
strongly recommends that you use tires
equivalent to the originals in size, quality and
performance when replacement is needed.
Refer to the paragraph on “Tread Wear Indi-
cators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle
Certification Label for the size designation of
your tire. The Load Index and Speed Symbol
for your tire will be found on the original
equipment tire sidewall.
It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s
handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifica-tions or capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
WARNING!
• Do not use a tire, wheel size, load rating,
or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and per-
formance characteristics, resulting in
changes to steering, handling, and brak-
ing of your vehicle. This can cause un-
predictable handling and stress to steer-
ing and suspension components. You
could lose control and have a collision
resulting in serious injury or death. Use
only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index
or capacity, other than what was origi-
nally equipped on your vehicle. Using a
tire with a smaller load index could re-
sult in tire overloading and failure. You
could lose control and have a collision.
WARNING!
• Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false speedom-
eter and odometer readings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all sea-
sons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identified
by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in
sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.

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/
45R20 110_ 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.
