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