about your tire warranty and where to obtain service, see
your Buick Warranty booklet for details.

are dangerous.

Overloading your tires can cause
overheating as a result of too much friction.

the Index.

Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires

when your tires are cold.
