Tires
We don't make tires. Your new vehicle
comes with high quality tires made by a
leading tire manufacturer. These tires
are warranted by the tire manufacturers
and their warranties are delivered with
every new Pontiac. If your spare tire is a
different brand than your road tires, you
will have a tire warranty folder from
each of these manufacturers.
