treadwear. Ratings are
determined by tire

Tire Pressure

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

Caution

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.
