I recently drove over freshly laid asphalt-I was not aware it was fresh and still hot, there weren't any construction signs. Needless to say, all four tires were coated in a thick layer of asphalt. I drove about 30 miles on this and it still hadn't all come off so I went to Discount to have the tires checked out and make sure it hadn't melted the tread. They pulled my car into the bay and scraped off as much as they could of the remaining asphalt! No charge! My car is new so the tires are original, no Discount Tires on it yet but they still did this service for me. I thought this was exemplary customer service and it's why I've used Discount Tire for years!
