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

Fuel Economy

Tread Wear

Ride Comfort and Vehicle Stability
Safety
Both under-inflation and over-inflation 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
Under-inflated 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. Over-inflation produces a
jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed
on the driver's side B-Pillar or rear edge of the
driver's side door.
At least once a month:

Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgment when determining
proper inflation. Tires may look properly
inflated even when they are under-inflated.

Inspect tires for signs of tire wear or visible
damage.
WARNING!

Improperly inflated tires are dangerous and
can cause collisions.

Under-inflation increases tire flexing and
can result in overheating and tire failure.

Over-inflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that result
in tire failure.

Over-inflated or under-inflated 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.
