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
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.
Both
underinflation
and
overinflation
affect
the
stability
of
the
vehicle

and
can
produce
a
feeling
of
sluggish
r
esponse
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.

tires

can
cause
abnormal
wear
patterns

and
reduced
tread

resulting
in
the
need
for

Ride
Comfort
And
Vehicle
Stability
Proper
tire
inflation
contributes
to
a
comfortable
ride.
Overinflation

produces
a
jarring
and
uncomfortable
ride.
TireInflation 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
determining
proper
inflation.
Tires
may
look
properly
inflated
even
when
they
are
underinflated.
• 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 minimum of three hours. The cold tire
inflation pressure must not exceed the maximum inflation pressure
molded into the tire sidewall.
Check tire pressures more often if subject to a wide range of outdoor
temperatures, as tire pressures vary with temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per 12°F (7°C) of air
temperature change. Keep this in mind when checking tire pressure
inside a garage, especially in the Winter.

If

Tire Pressures For High Speed Operation
The
manufacturer
advocates
driving
at
safe
speeds
and
within
posted

speed
limits.
Where
speed
limits
or
conditions
are
such
that
the
vehicle

can
be
driven
at
high
speeds,
maintaining
correct
tire
inflation
pressure
is

very
important.
Increased
tire
pressure
and
reduced
vehicle
loading
may

be
required
for
high
speed
vehicle
operation.
Refer
to
an
authorized
tire

dealer
or
original
equipment
vehicle
dealer
for
recommended
safe

operating
speeds,
loading


and
cold
tire
inflation
pressures.
WARNING!
High speed driving with your vehicle under maximum load is
dangerous. The added strain on your tires could cause them to fail.
You could have a serious collision. Do not drive a vehicle loaded to
the maximum capacity at continuous speeds above 75 mph
(120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types of tires on your vehicle
will cause your vehicle to handle poorly. The instability could cause
a collision. Always use radial ply tires in sets of four. Never combine
them with other types of tires.

Tire Repair
If your tire becomes damaged, it may be repaired if it meets the following
criteria:
•The tire has not been driven on when flat.
• The damage is only on the tread section of your tire (sidewall damage
is not repairable).
• The puncture is no greater thana¼ofaninch (6 mm).

Life Of Tire
The service life of a tire is dependent upon varying factors including, but
not limited to:
•˜ž›1 riving
style
ï
• Tire pressure - Improper cold tire inflation pressures can cause uneven
wear patterns to develop across the tire tread. These abnormal wear
patterns will reduce tread life, resulting in the need for earlier tire
replacement.
• ‘Ž1 –’•Žœ
driven.
• Performance tires, tires with a speed rating of V or higher, and
Summer tires typically have a reduced tread life. Rotation of these tires
per the vehicle scheduled maintenance is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six years, regardless
of the remaining tread. Failure to follow this warning can result in
sudden tire failure. You could lose control and have a collision
resulting in serious injury or death.
