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
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

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 pres-
sure.
262
Both underinflation and overinflation 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
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 consump-
tion.
can cause
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. Overinflation 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 judgement when deter-
mining proper inflation. Tires may look
properly inflated even when they are
under-inflated.
Inspect tires for signs of tire wear or visible

damage.
CAUTION!
After inspecting or adjusting the tire
pressure, always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which could
damage the valve stem.
Inflation pressures specified on the placard
are always "cold tire inflation pressure".
Cold tire inflation pressure is defined as the
tire pressure after the vehicle has not been
driven for at least three hours, or driven less
than 1 mile (1.6 km) after sitting for a
