Inflation - Tire Pressure
Tires need the correct amount of
air pressure to operate
effectively.
Notice: Do not let anyone tell
you that under-inflation or
over-inflation is all right. It is
not. If your tires do not have
enough air (under-inflation),
you can get the following:
• Too much flexing
• Too much heat
• Tire overloading
• Premature or irregular wear
• Poor handling
• Reduced fuel economy
If your tires have too much air
(over-inflation), you can get
the following:
• Unusual wear
• Poor handling
• Rough ride
• Needless damage from road
hazards
A vehicle specific Tire and
Loading Information label is
attached to the vehicle’s center
pillar, below the driver’s door
latch. This label lists the
vehicle’s original equipment tires
and the recommended cold
tire inflation pressure for the tires
when they are cold. The
recommended cold tire inflation
pressure, shown on the label,
is the minimum amount of air
pressure needed to support your
vehicle’s maximum load
carrying capacity. For more
information regarding how much
weight your vehicle can carry,
see Loading the Vehicle on
page 8-28.
How you load your vehicle
affects vehicle handling and ride
comfort. When driving with
less than the maximum load
capacity allowed for your vehicle,
you can set tire inflation
pressure to the recommended
amounts shown in the following
chart. Never load your vehicle
with more weight than it
was designed to carry.
