22 - 16 TIRES/WHEELS
TIRES (Continued)
STANDARD PROCEDURE
TIRE INFLATION PRESSURES
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. 23).

1 - THIN TIRE THREAD AREAS
Over inflation causes rapid center wear and loss of
the tire's ability to cushion shocks (Fig. 24).

Improper inflation can cause:
• Uneven wear patterns
• Reduced tread life
• Reduced fuel economy
• Unsatisfactory ride
• The vehicle to drift.
For proper tire pressure specification refer to the
Tire Inflation Pressure Chart Placard provided with
the vehicle.
Tire pressures have been chosen to provide safe
operation, vehicle stability, and a smooth ride. Tire
pressure should be checked cold once per month.
Check tire pressure more frequently when the
weather temperature varies widely. Tire pressure will
decrease when the outdoor temperature drops.
Inflation pressures specified on the placard is
always the cold inflation pressure of the tire. Cold
inflation pressure is obtained if the vehicle has not
been operated for at least 3 hours, or if 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 build-up.
TIRE PRESSURE FOR HIGH SPEED
OPERATION
WARNING: OVER OR UNDER INFLATED TIRES CAN
AFFECT VEHICLE HANDLING. THE TIRE CAN FAIL
SUDDENLY, RESULTING IN LOSS OF VEHICLE
CONTROL.
DaimlerChrysler Corporation advocates driving
this vehicle at safe speeds and within the posted
speed limits. Where speed limits allow the vehicle to
be driven at high speeds, the correct tire inflation
pressure is very important. For speeds up to and
including 120 km/h (75 mph), tires must be inflated
to the pressures shown on the label applied to the
rear facing of the driver's door. For continuous speeds
in excess of 120 km/h (75 mph), tires must be
inflated to the maximum pressure specified on the
tire's sidewall.
TIRE LEAK REPAIRING
For proper repairing, a radial tire must be removed
from the wheel and repaired (patched) from the
inside of the tire. Repairs should only be made if the
defect, or puncture, is in the tread area (Fig. 25) of
the tire. The tire should be replaced if the puncture
is located in the sidewall.
Deflate tire completely before dismounting the tire
from the wheel. Use a lubricant such as a mild soap
solution when dismounting or mounting the tire.
When dismounting the tire from the rim, only use
tools free of burrs or sharp edges which could dam-
age the tire or the wheel.
Before mounting the tire on the wheel, make sure
all dirt and/or oxidation is removed from the bead of
the wheel.
