Tire Pressure

Tires need the correct amount of
air pressure to operate
effectively.

{

Warning

Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:

.

Tire overloading and
overheating, which could
lead to a blowout.

.

Premature or

irregular wear.

.

Poor handling.

.

Reduced fuel economy.

Overinflated tires, or tires that
have too much air, can
result in:

.

Unusual wear.

.

Poor handling.

.

Rough ride.

.

Needless damage from
road hazards.
