Jeep Commander (2010 year). Instruction

Tire Identification Number (TIN)

The TIN may be found on one or both sides of the tire,
however, the date code may only be on one side. Tires
with white sidewalls will have the full TIN, including the
date code, located on the white sidewall side of the tire.

Look for the TIN on the outboard side of black sidewall
tires as mounted on the vehicle. If the TIN is not found on
the outboard side, then you will find it on the inboard
side of the tire.

EXAMPLE:

DOT MA L9 ABCD 0301

DOT

= Department of Transportation

— This symbol certifies that the tire is in compliance with the U.S. Department of Transportation tire
safety standards and is approved for highway use

= Code representing the tire manufacturing location (two digits)

Tire Loading and Tire Pressure

Tire Placard Location

NOTE:

The proper cold tire inflation pressure is listed

on the driver’s side B-Pillar.

Tire and Loading Information Placard

This placard tells you important information about
the:
1) number of people that can be carried in the vehicle
2) total weight your vehicle can carry
3) tire size designed for your vehicle
4) cold tire inflation pressures for the front, rear, and
spare tires.

Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire’s load carrying capacity if you
adhere to the loading conditions, tire size, and cold tire
inflation pressures specified on the Tire and Loading
Information placard and in the “Vehicle Loading” section
of this manual.

Tire and Loading Information Placard

290

STARTING AND OPERATING

NOTE:

Under a maximum loaded vehicle condition,

gross axle weight ratings (GAWRs) for the front and rear
axles must not be exceeded. For further information on
GAWRs, vehicle loading, and trailer towing, refer to
“Vehicle Loading” in this section.

To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX lbs or
XXX kg” on the Tire and Loading Information placard.
The combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.

Steps for Determining Correct Load Limit

1. Locate the statement “The combined weight of occu-
pants and cargo should never exceed XXX lbs or XXX kg”
on your vehicle’s placard.

2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.

3. Subtract the combined weight of the driver and pas-
sengers from XXX lbs or XXX kg.

4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if “XXX”
amount equals 1,400 lbs (635 kg) and there will be five
150 lb (68 kg) passengers in your vehicle, the amount of
available cargo and luggage load capacity is 650 lbs
(295 kg) (since 5 x 150 = 750, and 1400 – 750 = 650 lbs
[295 kg]).

5. Determine the combined weight of luggage and cargo
being loaded on the vehicle. That weight may not safely
exceed the available cargo and luggage load capacity
calculated in Step 4.

STARTING AND OPERATING

291

6. If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. Consult this
manual to determine how this reduces the available
cargo and luggage load capacity of your vehicle.

NOTE:

• The following table shows examples on how to calcu-

late total load, cargo/luggage, and towing capacities
of your vehicle with varying seating configurations
and number and size of occupants. This table is for
illustration purposes only and may not be accurate for
the seating and load carry capacity of your vehicle.

• For the following example, the combined weight of

occupants and cargo should never exceed 865 lbs
(392 kg).

292

STARTING AND OPERATING

WARNING!

Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.

TIRES — GENERAL INFORMATION

Tire Pressure

Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:

Safety

WARNING!

• Improperly inflated tires are dangerous and can

cause accidents.

• Under-inflation increases tire flexing and can re-

sult in over-heating and tire failure.

• Over-inflation reduces a tire’s ability to cushion

shock. Objects on the road and chuckholes can
cause damage that result in tire failure.

• Unequal tire pressures can cause steering prob-

lems. You could lose control of your vehicle.

• Over-inflated or under-inflated tires can affect

vehicle handling and can fail suddenly, resulting
in loss of vehicle control.

(Continued)

294

STARTING AND OPERATING

WARNING! (Continued)

• Unequal tire pressures from one side of the ve-

hicle to the other can cause the vehicle to drift to
the right or left.

• Always drive with each tire inflated to the recom-

mended cold tire inflation pressure.

Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under-inflation also increases
tire rolling resistance and results in higher fuel
consumption.

Ride Comfort and Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride. Both under-inflation and over-inflation affect the

stability of the vehicle and can produce a feeling of
sluggish response or over responsiveness in the steering.

Unequal tire pressures can cause erratic and unpredict-
able steering response.

Unequal tire pressure from side to side may cause the
vehicle to drift left or right.

Tire Inflation Pressures

The proper cold tire inflation pressure is listed on the
driver’s side “B” Pillar.

The pressure should be checked and adjusted, as well as
inspected for signs of tire wear or visible damage, at least
once a month. Use a good quality pocket-type gauge to
check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are under-inflated.

STARTING AND OPERATING

295

CAUTION!

After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap (if equipped). This
will prevent moisture and dirt from entering the
valve stem, which could damage it.

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 a three-hour period. 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.

Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build-up, or your tire pressure will be too low.

296

STARTING AND OPERATING

Tire Pressures For High Speed Operation

The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.

WARNING!

High speed driving with your vehicle at or above
maximum load is dangerous. The added strain on
your tires could cause them to fail. You could have a
serious accident. Do not drive a vehicle loaded to the
maximum capacity at continuous speeds above
75 mph (120 km/h).

Radial-Ply Tires

WARNING!

Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial tires in sets of four. Never combine
them with other types of tires.

Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized dealer for radial tire repairs.

Compact Spare Tire — If Equipped

The compact spare is for temporary emergency use with
radial tires. It is engineered to be used on your style
vehicle only. Since this tire has limited tread life, the
original tire should be repaired (or replaced) and rein-
stalled at the first opportunity.

STARTING AND OPERATING

297

WARNING!

Temporary use spare tires are for emergency use only.
With these tires, do not drive more than 50 mph
(80 km/h). Temporary use spare tires have limited
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.

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.

Do not install more than one compact spare tire/wheel
on the vehicle at any given time.

CAUTION!

Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with the
compact spare installed. Damage to the vehicle may
result.

Tire Spinning

When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels above 35 mph (55 km/h).

298

STARTING AND OPERATING

WARNING!

Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure some-
one. Do not spin your vehicle’s wheels faster than
35 mph (55 km/h) when you are stuck, and do not let
anyone near a spinning wheel no matter what the
speed.

Tread Wear Indicators

Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 in (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced.

Life of Tire

The service life of a tire is dependent upon various
factors including but not limited to:

• Driving style
• Tire pressure
• Distance driven

WARNING!

Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have an accident resulting
in serious injury or death.

Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.

Replacement Tires

The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. (Refer to the paragraph on
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” placard for the size designation of your
tires. The service description and load identification will
be found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.

300

STARTING AND OPERATING

WARNING!

• Do not use a tire, wheel size or rating other than

that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
an accident 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 than what was originally equipped on
your vehicle. Using a tire with a smaller load index
could result in tire overloading and failure. You
could lose control and have an accident.

(Continued)

WARNING! (Continued)

• 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 speedometer and odometer read-
ings.

TIRE CHAINS

Only models fitted with 235/65R17XL (extra load) tires
have sufficient tire-to-body clearance to allow use of tire
chains. Install chains on rear tires only. Follow these
recommendations to guard against damage and exces-
sive tire and chain wear:

STARTING AND OPERATING

301

• For vehicles equipped with 18 inch wheels, do not

install tire chains or traction devices on tires larger
than 235/60R18XL. Tires larger than this may not
provide sufficient body clearance with chains or other
traction devices.

• Manufacturer recommends a cold inflation pressure of

38 psi (262 kPa) when using 235/65R17XL size tires for
this vehicle.

• Use SAE class “S” tire chains or traction devices only.
• Follow tire chain manufacturer’s instructions for

mounting chains.

• Install chains snugly and tighten after 1/2 mi (1 km) of

driving.

• Do not exceed 30 mph (48 km/h), unless otherwise

specified by the chain manufacturer.

• Drive cautiously, avoiding large bumps, potholes and

extreme driving maneuvers.

TIRE ROTATION RECOMMENDATIONS

Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates and develop irregular wear patterns.

These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on On/Off-Road
type tires. Rotation will increase tread life, help to main-
tain mud, snow, and wet traction levels, and contribute to
a smooth, quiet ride.

Refer to “Maintenance Schedule” in Section 8 of this
manual for the proper maintenance intervals. More fre-
quent rotation is permissible if desired. The reasons for
any rapid or unusual wear should be corrected prior to
rotation being performed.

302

STARTING AND OPERATING

NOTE:

The premium Tire Pressure Monitor System will

automatically locate the pressure values displayed in the
correct vehicle position following a tire rotation.

The suggested rotation method is the “forward-cross”
shown in the following diagram.

TIRE PRESSURE MONITOR SYSTEM (TPMS)

The Tire Pressure Monitoring System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold tire pressure.

The tire pressure will vary with temperature by about
1 psi (7 kPa) for every 12°F (–11°C). This means that when
the outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This 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 a
three-hour period. Refer to the “Tires – General Infor-
mation” in this section for information on how to
properly inflate the vehicle’s tires.

The tire pressure will

also increase as the vehicle is driven - this is normal and
there should be no adjustment for this increased pres-
sure.

Tire Rotation

STARTING AND OPERATING

303

The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low pressure warning
threshold for any reason, including low temperature
effects, or natural pressure loss through the tire.

The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above recommended
cold tire pressure. Once the low tire pressure warning has
been illuminated, the tire pressure must be increased to
the recommended cold tire pressure in order for the Tire
Pressure Monitoring Telltale Light to be turned off. The
system will automatically update and the Tire Pressure
Monitoring Telltale Light will extinguish once the up-
dated tire pressures have been received. The vehicle may
need to be driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.

For example, your vehicle has a recommended cold
(parked for more than three hours) tire pressure of 33 psi
(227 kPa). If the ambient temperature is 68°F (20°C) and
the measured tire pressure is 28 psi (193 kPa), a tempera-
ture drop to 20°F (-7°C) will decrease the tire pressure to
approximately 24 psi (165 kPa). This tire pressure is
sufficiently low enough to turn ON the Tire Pressure
Monitoring Telltale Light. Driving the vehicle may cause
the tire pressure to rise to approximately 28 psi (193 kPa),
but the Tire Pressure Monitoring Telltale Light will still
be ON. In this situation, the Tire Pressure Monitoring
Telltale Light will turn OFF only after the tires have been
inflated to the vehicle’s recommended cold tire pressure
value.
