Dodge Durango (HB). Manual — part 1369
An All Season type tire will have either M + S, M & S or M–S (indicating mud and snow traction) imprinted on the
side wall.
TIRE CHAINS
Tire snow chains may be used on certain models. Refer to the Owner’s Manual for more information.
RADIAL-PLY TIRES
Radial-ply tires improve handling, tread life and ride quality, and decrease rolling resistance.
Radial-ply tires must always be used in sets of four. Under no circumstances should they be used on the front only.
They may be mixed with temporary spare tires when necessary. A maximum speed of 50 MPH is recommended
while a temporary spare is in use.
Radial-ply tires have the same load-carrying capacity as other types of tires of the same size. They also use the
same recommended inflation pressures.
The use of oversized tires, either in the front or rear of the vehicle, can cause vehicle drive train failure. This could
also cause inaccurate wheel speed signals when the vehicle is equipped with Anti-Lock Brakes.
The use of tires from different manufactures on the same vehicle is NOT recommended. The proper tire pressure
should be maintained on all four tires.
TIRE INFLATION PRESSURES
WARNING: OVER OR UNDER INFLATED TIRES
CAN AFFECT VEHICLE HANDLING AND TREAD
WEAR. THIS MAY CAUSE THE TIRE TO FAIL SUD-
DENLY, RESULTING IN LOSS OF VEHICLE CON-
TROL.
Under inflation will cause rapid shoulder wear (1), tire
flexing, and possible tire failure.
Over inflation will cause rapid center wear (1) and loss
of the tire’s ability to cushion shocks.

Improper inflation can cause:
•
Uneven wear patterns
•
Reduced tread life
•
Reduced fuel economy
•
Unsatisfactory ride
•
Vehicle drift
For proper tire pressure specification refer to the vehicles Owners Manual.
TIRE PRESSURE FOR HIGH SPEED
Refer to the Vehicles Owners Manual package.
SPARE / TEMPORARY TIRE
The temporary spare tire is designed for emergency use only. The original tire should be repaired or replaced at the
first opportunity, then reinstalled. Do not exceed speeds of 50 M.P.H. when using the temporary spare tire. Refer to
Owner’s Manual for complete details.
FULL SIZE, SPARE WHEEL WITH MATCHING TIRE
The spare is a full usage wheel with a matching tire, It can be used within the (posted legal) speed limits or distance
limitations as of the rest of the vehicles four tires. Refer to Owner’s Manual for complete details.
REPLACEMENT TIRES
The original equipment tires provide a proper balance of many characteristics such as:
•
Ride
•
Noise
•
Handling
•
Durability
•
Tread life
•
Traction
•
Rolling resistance
•
Speed capability
It is recommended that tires equivalent to the original 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 use of oversize tires may cause interference with vehicle components. Under extremes of suspension and
steering travel, interference with vehicle components may cause tire damage.
WARNING: FAILURE TO EQUIP THE VEHICLE WITH TIRES HAVING ADEQUATE SPEED CAPABILITY CAN
RESULT IN SUDDEN TIRE FAILURE.
DIAGNOSIS AND TESTING
PRESSURE GAUGES
A quality air pressure gauge is recommended to check tire pressure. After checking the air pressure, replace valve
cap finger tight.

TREAD WEAR INDICATORS
Tread wear indicators (3) are molded into the bottom
of the tread grooves. When tread depth is 1.6 mm
(1/16 in.), the tread wear indicators (3) will appear as
a 13 mm (1/2 in.) band.
Tire replacement is necessary when indicators appear
in two or more grooves or if localized balding occurs.
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.
Excessive toe-in or toe-out causes wear on the tread edges and a feathered effect across the tread.
TIRE NOISE OR VIBRATION
Radial-ply tires are sensitive to force impulses caused by improper mounting, vibration, wheel defects, or possibly
tire imbalance.
To find out if tires are causing the noise or vibration, drive the vehicle over a smooth road at varying speeds. Note
the noise level during acceleration and deceleration. The engine, differential and exhaust noises will change as
speed varies, while the tire noise will usually remain constant.
