in improved fuel economy. For those owners who prefer the utmost
in comfort, the optional tire pressures listed on the placard may be used.
I ncorrect tire inflation pressures can have adverse affects
on tire life and
vehicle performance. Too Iowan air pressure causes increased tire flexing
and heat build-up. This weakens the tire and increases the chance
of
damage or failure. It can result in tire overloading, abnormal tire wear,
adverse vehicle handling, and reduced fuel
mileage, Too high an air
pressure can result in abnormal wear, harsh ride, and also increase the
chance
of damage from road hazards.
Tire inflation pressures should be checked (this includes the spare tire,
unless it
is a stowaway spare) at least monthly and when significantly
