Tire Pressure
Proper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Four primary areas are affected by improper tire
pressure:

Safety

Fuel Economy

Tread Wear

Ride Comfort And Vehicle Stability
Safety Both underinflation and overinflation affect the
stability of the vehicle and can produce a feeling
of sluggish response or over responsiveness in
the steering.
NOTE:

Unequal tire pressures from side to side may
cause erratic and unpredictable steering
response.

Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause
abnormal wear patterns and reduced tread life,
resulting in the need for earlier tire
replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a
comfortable ride. Overinflation produces a
jarring and uncomfortable ride.
WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your stopping
distance. Use tires of the recommended load
capacity for your vehicle. Never overload
them.
WARNING!

Improperly inflated tires are dangerous and
can cause collisions.

Underinflation increases tire flexing and
can result in overheating and tire failure.

Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that result
in tire failure.

Overinflated or underinflated tires can
affect vehicle handling and can fail
suddenly, resulting in loss of vehicle
control.

Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.

Unequal tire pressures from one side of the
vehicle to the other can cause the vehicle
to drift to the right or left.

Always drive with each tire inflated to the
recommended cold tire inflation pressure.
