Just looked at the paperwork. In our last rig, a DP that came with Michelin 235/80/22.5, we put on Toyo M154 245/75/22.5. Yokohama may or may not have a replacement. Call or email Yoko and ask. Let us know. I have pretty new Michelins 255/80/22.5 on our new rig. Hope to find Toyo or Yokohama replacements when the time comes. Don't want to pay 600 bucks a tire if I can help it.
