 Austin Sindrick here, driver of the number two discount tire Ford Mustang, to give you a quick message about tire safety. As a professional driver, safety and winning go hand in hand. That's why we make pit stops. Off the track, I regularly check my tires and wheels too. Stop by a local tire retailer for a tire safety check on your vehicle, or do a quick check of your tire's tread with a penny test at home. A message from the U.S. Tire Manufacturers Association.
