Just went through the "replace tires" thing for my MH. I did tons of research and came up with TOYO tires to save a little over the Goodyears or Michelins. I'm totally satisfied with my purchase. My though is that the Goodyear or Michelin name drives price up somewhat. I'm not saying they are not an excellent tire; but it does not mean there are not other excellent choices. I looked at the DC tires as well, could not find enough info on them.
Good luck with your choice.
