2006 JEEP WRANGLER wheel size

ORC detects a malfunction, the “Airbag Warning
Light” will illuminate for a minimum of 12 seconds
and will remain illuminated as long as the malfunction
exists.
WARNING!
Ignoring the “Airbag Warning Light” in your instru-
ment panel could mean you won’t have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
•The Driver and Passenger Airbag/Inflator Units are
located in the center of the steering wheel and in the
instrument panel. When the ORC detects a collision
requiring the airbags, it signals the inflator units. A
large quantity of nontoxic gas is generated to inflate the airbags. The airbag covers separate and fold out of
the way as the bags inflate to full size. The bags fully
inflate in about 50 milliseconds. This is about half of
the time it takes to blink your eyes. The airbags then
quickly deflate while helping to restrain the driver and
front passenger. The driver’s front airbag gas is vented
through the airbag material towards the instrument
panel. The passenger’s front airbag gas is vented
through vent holes in the sides of the airbag. In this
way the airbags do not interfere with your control of
the vehicle.
•The
Knee Impact Bolsters help protect the knees and
position the driver and front passenger’s for the best
interaction with the front airbag.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 31
2

Proper operation of four wheel drive vehicles depends on
tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
Shift Positions
For additional information on the appropriate use of each
transfer case mode position, see the information below:

highway driving. Dry hard surfaced roads.
196 STARTING AND OPERATING

WARNING!
To help avoid personal injury, follow these tips:
•Never reach through the steering wheel to operate
steering column controls. Injury to your hands or
loss of vehicle control may result.
•If the engine stalls or power assist fails due to a
malfunction, vehicle steering and braking will
require greater effort.
ANTI-LOCK BRAKE SYSTEM — IF EQUIPPED
The Anti-Lock Brake System is designed to aid the driver
in maintaining vehicle control under adverse braking
conditions. The system operates with a separate com-
puter to modulate hydraulic pressure to prevent wheel
lock-up and help avoid skidding on slippery surfaces. All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
WARNING!
Significant over or under-inflation of tires, or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.
The Anti-Lock Brake System conducts a low speed self-
test at about 12 mph (20 km/h). If for any reason, your
foot is on the brake when the vehicle reaches 12 mph (20
km/h), this check will be delayed until 25 mph (40
km/h).

WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of un-
approved tires and wheels may change suspension
dimensions and performance characteristics, resulting
in changes to steering, handling, and braking of your
vehicle. This can cause unpredictable handling and
stress to steering and suspension 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,
other 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.
•Failure to equip your vehicle with tires having ad-
equate 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.
Alignment and Balance
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
STARTING AND OPERATING 227

Tires may also cause the vehicle to pull left or right.
Alignment will not correct this problem. See your autho-
rized dealer for proper diagnosis.
Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
TIRE CHAINS
Install chains on rear tires only. Tire chains may be
installed on all models except the Sahara and Rubicon.
Follow these recommendations to guard against damage
and excessive tire and chain wear:
•Use chains on P215/75R15 tires only. P225/75R15,
LT30 x 9.50R15, and LT245/75R16 tires do not provide
adequate clearance.
•Use SAE class “S” tire chains or traction devices only.
•Chains must be the proper size for the vehicle, as
recommended by the chain manufacturer.
•Follow tire chain manufacturer’s instructions for
mounting chains.
•Install chains snugly and tighten after.6 mile (1 km) of
driving.
•Do not exceed 30 mph (48 km/h).
•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.
