(underinflation), 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 (overinfla tion),
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 recommen ded 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 the Vehicle
on page 524
. How you load
your vehicle affects vehicle handling and ride
comfort. Never load your vehicle with more weight
than it was designed to carry.

forget to check the compact spare tire, it should
