CHRYSLER VOYAGER 2001 Service Manual

Performance tires will have a speed rating letter
after the aspect ratio number. For example, the letter
ªSº indicates that the tire is speed rated up to 112
mph (180 km/h). The speed rating is not always
printed on the tire sidewall.
²Q -up to 100 mph (160 km/h)
²S -up to 112 mph (180 km/h)
²T -up to 118 mph (190 km/h)
²U -up to 124 mph (200 km/h)
²H -up to 130 mph (210 km/h)
²V -up to 149 mph (240 km/h)
²Z -more than 149 mph (240 km/h) (consult the
tire manufacturer for the specific speed rating)
An All Season type tire will have eitherM+S,M
& S or M-S (indicating mud and snow traction)
imprinted on the side wall.
TIRE CHAINS
Refer to the owners manual supplied with the vehi-
cle to determine whether the use of tire chains is per-
mitted on this vehicle.
DESCRIPTION - RADIAL-PLY TIRES
Radial-ply tires improve handling, tread life, ride
quality and decrease rolling resistance.
Radial-ply tires must always be used in sets of four
and under no circumstances should they be used on
the front only. It is recommended that tires from dif-
ferent manufacturers NOT be mixed. They may bemixed with a temporary spare tire when necessary. A
maximum speed of 80 km/h (50 mph) is recom-
mended while a temporary spare is in use.
Radial-ply tires have the same load-carrying capac-
ity as other types of tires of the same size. They also
use the same recommended inflation pressures.
DESCRIPTION - REPLACEMENT TIRES
WARNING: FAILURE TO EQUIP THE VEHICLE WITH
TIRES HAVING ADEQUATE SPEED CAPABILITY
CAN RESULT IN SUDDEN TIRE FAILURE.
It is recommended that tires equivalent to the orig-
inal equipment tires be used when replacement is
needed.
Failure to use equivalent replacement tires may
adversely affect the safety and handling of the vehicle.
The original equipment tires provide a proper com-
bination of many characteristics such as:
²Ride
²Noise
²Handling
²Durability
²Tread life
²Traction
²Rolling resistance
²Speed capability
The use of oversize tires may cause interference
with vehicle components. Under extremes of suspen-
sion and steering travel, interference with vehicle
components may cause tire damage.
DESCRIPTION - SPARE TIRE (TEMPORARY)
The temporary (convenience) spare tire is designed
for emergency use only. The original tire should be
repaired and reinstalled, or replaced with a new, at
the first opportunity.
The temporary (convenience) spare tire should be
inflated to the pressure listed on its sidewall. Do not
exceed speeds of 80 km/h (50 mph) when the tempo-
rary spare tire is in use on the vehicle. Refer to the
Owner's Manual for more details.
DIAGNOSIS AND TESTING - TIRE NOISE
Unusual tire noise can be associated with tire and
wheel vibration or irregular tire wear. For vibration,
(Refer to 22 - TIRES/WHEELS - DIAGNOSIS AND
TESTING). For irregular tire wear, (Refer to 22 - TIRES/
WHEELS/TIRES - DIAGNOSIS AND TESTING).
DIAGNOSIS AND TESTING - TIRE/VEHICLE
LEAD
Use the following Vehicle Lead Diagnosis And Cor-
rection Chart to diagnose and correct a vehicle lead
or drift problem.

DIAGNOSIS AND TESTING - TIRE WEAR
PATTERNS
Under inflation will cause wear on the shoulders of
tire. Over inflation will cause wear at the center of
tire.
Excessive camber causes the tire to run at an
angle to the road. One side of tread is then worn
more than the other (Fig. 18).
Excessive toe-in or toe-out causes wear on the
tread edges and a feathered effect across the tread
(Fig. 18).
DIAGNOSIS AND TESTING - TREAD WEAR
INDICATORS
Tread wear indicators are molded into the bottom
of the tread grooves. When tread depth is 1.6 mm
(1/16 in.), the tread wear indicators will appear as a
13 mm (1/2 in.) band (Fig. 19).
Tire replacement is necessary when indicators
appear in two or more grooves or if localized balding
occurs.
STANDARD PROCEDURE - TIRE INFLATION
PRESSURES
The specified tire pressures have been chosen to
provide safe operation, vehicle stability, and a smooth
ride. The proper tire pressure specification can be
found on the Tire Inflation Pressure Label provided
with the vehicle (usually on the rear face inside the
glove box).
A quality air pressure gauge is recommended to
check tire air pressure. Tire pressure should be
checked cold once per month. Check tire pressure
more frequently when the weather temperature var-
ies widely. Tire pressure will decrease when the out-door temperature drops. After checking the air
pressure, replace valve cap finger tight.
Inflation pressures specified on the Tire Inflation
Pressure Label are always the cold inflation pressure
of the tire. Cold inflation pressure is obtained after
the vehicle has not been operated for at least 3
hours, or the vehicle is driven less than one mile
after being inoperative for 3 hours. Tire inflation
pressures may increase from 2 to 6 pounds per
square inch (psi) during operation. Do not reduce this
normal pressure buildup.

TIRES (Continued)

Improper inflation can cause:
²Uneven wear patterns
²Reduced tread life
²Reduced fuel economy
²Unsatisfactory ride
²The vehicle to drift.
WARNING: OVER OR UNDER INFLATED TIRES CAN
AFFECT VEHICLE HANDLING. THE TIRE CAN FAIL
SUDDENLY, RESULTING IN LOSS OF VEHICLE
CONTROL.
Under inflation causes rapid shoulder wear, tire
flexing, and can result in tire failure (Fig. 20).
Over inflation causes rapid center wear and loss of
the tire's ability to cushion shocks (Fig. 21).STANDARD PROCEDURE - TIRE PRESSURE
FOR HIGH SPEED OPERATION
DaimlerChrysler Corporation advocates driving at
safe speeds within posted speed limits. Where speed
limits allow the vehicle to be driven at high speeds,
correct tire inflation pressure is very important.
Vehicles loaded to maximum capacity should not be
driven at continuous speeds over 120 km/h (75 mph).
Never exceed the maximum speed capacity of the
tire. For information on tire identification and speed
ratings, (Refer to 22 - TIRES/WHEELS/TIRES -
DESCRIPTION).
STANDARD PROCEDURE - TIRE LEAK
REPAIRING
For proper repairing, a radial tire must be removed
from the wheel. Repairs should only be made if the
defect, or puncture, is in the tread area (Fig. 22). The
tire should be replaced if the puncture is located in
the sidewall.
Deflate tire completely before attempting to dis-
mount the tire from the wheel.Use a lubricant
such as a mild soap solution when dismounting
or mounting tire.Use tools free of burrs or sharp
edges which could damage the tire or wheel rim.
Before mounting tire on wheel, make sure all rust
is removed from the rim bead and repaint if neces-
sary.
Install wheel on vehicle, and progressively tighten
the 5 wheel nuts to a torque of 135 N´m (100 ft. lbs.).

CLEANING - TIRES
Before delivery of a vehicle, remove the protective
coating on the tires with white sidewalls or raised
white letters. To remove the protective coating, apply
warm water and let it soak for a few minutes. After-
wards, scrub the coating away with a soft bristle
brush. Steam cleaning may also be used to remove
the coating.
CAUTION: DO NOT use gasoline, mineral oil, oil-
based solvent or a wire brush for cleaning.
WHEELS
DESCRIPTION - WHEEL
Original equipment wheels are designed for proper
operation at all loads up to the specified maximum
vehicle capacity.
All models use either steel or aluminum drop-cen-
ter wheels. Every wheel has raised sections between
the rim flanges and rim drop well called safety
humps (Fig. 23). Initial inflation of the tires forces
the bead over these raised sections. In case of air
loss, the safety humps hold the tire in position on the
wheel until the vehicle can be brought to a safe stop.
Cast aluminum wheels require special balance
weights to fit on the flange of the rim (Fig. 24).
When wheel alignment is necessary on a vehicle
with cast aluminum wheels, special wheel clamps are
required to avoid damage to the wheel's finish.The wheel studs and nuts are designed for specific
wheel applications and must be replaced with equiv-
alent parts.
All aluminum wheels have wheel mounting (lug)
nuts with an enlarged nose. This enlarged nose is
necessary to ensure proper retention of the wheels.
DIAGNOSIS AND TESTING - WHEEL
INSPECTION
Inspect wheels for:
²Excessive runout
²Dents, cracks or irregular bends
²Damaged wheel stud (lug) holes
²Air Leaks
NOTE: Do not attempt to repair a wheel by hammer-
ing, heating or welding.
If a wheel is damaged, an original equipment
replacement wheel should be used. When obtaining
replacement wheels, they should be equivalent in
load carrying capacity. The diameter, width, offset,
pilot hole and bolt circle of the wheel should be the
same as the original wheel.
WARNING: FAILURE TO USE EQUIVALENT
REPLACEMENT WHEELS MAY ADVERSELY
AFFECT THE SAFETY AND HANDLING OF THE
VEHICLE.
WARNING: REPLACEMENT WITH USED WHEELS IS
NOT RECOMMENDED. THE SERVICE HISTORY OF
THE WHEEL MAY HAVE INCLUDED SEVERE TREAT-
MENT OR VERY HIGH MILEAGE. THE RIM COULD
FAIL WITHOUT WARNING.

CLEANING - ALUMINUM WHEEL CARE
Chrome plated and painted aluminum wheels
should be cleaned regularly using mild soap and
water to maintain their luster and to prevent corro-
sion.
Care must be taken in the selection of tire and
wheel cleaning chemicals and equipment to prevent
damage to the wheels. Any of the ªDO NOT USEº
items listed below WILL damage chrome plated and
painted aluminum wheels.
DO NOT USE:
²any abrasive metal cleaner
²any abrasive cleaning pad or brush
²any cleaner that contains an acid (this will
immediately react with and discolor the chromium
surface)
²chrome polish (unless it is buffed off immedi-
ately after application)
²oven cleaner
²a car wash that uses carbide-tipped wheel clean-
ing brushes
