WARNING!

Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your stop-
ping distance. Use tires of the recom-
mended load capacity for your vehicle.
Never overload them.

Tires — General Information

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 and Vehicle Stability

• Economy

• Tread Wear

• Ride Comfort

Safety

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 re-
sult in tire failure.

• Overinflated or underinflated tires can

affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle con-
trol.

• Unequal tire pressures can cause steer-

ing 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.

Both under-inflation and over-inflation affect
the stability of the vehicle and can produce a
feeling of sluggish response or over respon-
siveness in the steering.

NOTE:

• Unequal tire pressures from side to side

may cause erratic and unpredictable steer-
ing 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 consump-
tion.

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 comfort-
able ride. Over-inflation produces a jarring
and uncomfortable ride.
