Tires
Inflation - Tire Pressure
Tires need the correct amount of air pressure to operate
effectively.
Notice:

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
