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 your vehicle. 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 4-28. 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. For additional information
regarding the compact spare tire, see Compact
Spare Tire on page 5-66.
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).
