You're gonna love this. When I had brake/bearing/tire failure last October just west of Kingsport, TN., the Goodyear tire store less than a mile away from the RV center doing the repairs had Maxxis or Marathon. I chose the Maxxis to make the rest of the trip to Fredericksburg, VA. and back to Tullahoma, TN. I have since replaced the rest of the Marathons with Maxxis.
