Good helpful folks. Received oil change and tire rotation. One tire was not holding air very well. They found a screw in the tire and said it was too close to the sidewall to patch. I asked to see the tire and they accommodated my request. To me it looked like the screw was not really near the sidewall; however, I trust the technicians analysis. Now I know that the sidewall extends further into the bottom of the tire than I expected.
