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 Tire and Loading Information label is attached
to the vehicle’s center pillar. This label lists your
vehicle’s original equipment tires and shows the
correct inflation pressures for your 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 additional information regarding how much
weight your vehicle can carry, and an example
of the Tire and Loading Information label,
see Loading Your Vehicle on page 4-20. How you
load your vehicle affects the vehicle handling
and ride comfort, never load your vehicle
with more weight than it was designed to carry.
When to Check
Check your tires once a month or more.
Do not forget to check the spare tire. If your
vehicle has a compact spare tire, it should be
at 60 psi (420 kPa). For additional information
see Spare Tire on page 5-86.
