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, below the driver’s door latch
or inside the glove box. This label lists your vehicle’s
original equipment tires and their recommended cold
tire inflation pressures. 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 4-33. How you load your vehicle affects
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 compact spare tire, it should be at 60 psi
(420 kPa). For additional information regarding the
compact spare tire, see Compact Spare Tire on
page 5-86.
