And if they see something embedded in the tire, it's removed and the hole is plugged as just part of the service. No extra charge for that. In fact, if one of your tires is low, stop by and they'll be happy to check that out for free. That's part of what they've been doing at Don Duncan. They'd like to be that go-to place for you.
