We bought a 2002 Newmar Kountry Star a few years ago, our first motorhome. I learned more about tires and the DOT code and had to buy new tires last year. I bought the Michelins through the FMCA tire program. Although we dropped about 3 grand it was worth it for the ride and sense of security knowing we had the best tires we could buy on the coach. I wasn't willing to take any chances on a cheaper tire when the drive tires are so valuable. If one of those goes there could be terrible consequences. Good luck in your decision making process.
