Safety
WARNING!
• Improperly inflated tires are dangerous and can
cause accidents.
• Under inflation increases tire flexing and can
result in tire failure.
• Over inflation reduces a tire’s ability to cushion
shock. Objects on the road and chuck holes can
cause damage that results in tire failure.
• Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
• Overinflated or under inflated tires can affect
vehicle handling and can fail suddenly, resulting
in loss of vehicle control.

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 properly inflated.
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
