Joe and Carl--From your brief post I sense this a rat hole others have gone down over the years. As a new owner of a used motorhome, 2002 Newmar Dutch Star, buying my first set of tires have learned that I did not know the right questions to ask and then not following-up before tires were installed. I have not given up quest to get newer tires, almost two years is not acceptable. Tire store has been instructed to hold my old tires, made Oct or Nov 2012 with less than 12,000 always covered, and if required/necessary will have them put back on motorhome and live to fight another day.
