I had the RoughRider M + S m on my Expy before I put my 35's on. I also ran them on my old Explorer. They were awesome on the mud, ice and snow, but lived up to there name for being rough. Very loud, and you can feel every tread when your driving. But for the $$$$ thet were pretty darn good. If they made them in a 35 inch, I probably would have bought a set, and saved myself a few hundred dollars compared to the Hankooks. But I really love these Dynapros I'm running now too.
