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 (B-pillar), below the driver’s
door latch. This label shows your vehicle’s original
equipment tires and 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 4-29. 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.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are properly inflated
simply by looking at them. Radial tires may look properly
inflated even when they are under-inflated. Check the
tire’s inflation pressure when the tires are cold. Cold
means your vehicle has been sitting for at least
three hours or driven no more than 1 mile (1.6 km).
