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:
Tire overloading and
over-heating which could
lead to a blowout.
Premature or
irregular wear.
Poor handling.
Reduced fuel economy.
