[John B] Comeing near to needing a new set (6) of tires for my class A Gulfstream Sunsport. A mechanic looked at my vehicle and suggested that the only good tire I had on it was a poor choice. It was a Michelin. He said that they were possible the worst to use on my Class of vehicle. Anybody have any suggestions on what tire is best for use on my MH and why is Michelin a bad choice.
