After driving for 6 hours I got a flat. Fortunately but sometimes unfortunately I have run flats. I was towed to this store just before they closed. (Didn't want to chance driving so slow on the interstate). Gene was very helpful and understanding. Stores don't always carry run flats (that's the unfortunate part) and I was so happy they had one. He verified it was the correct one and within 15 minutes I was back in the road for the rest of my 2 hour drive.
