I tried with the West Coast Heindau dealer for a 180/80 -14. I showed him the rear tire on the TW. I told him only Bridgestone and Shinko made them. I said people were using ATV tires because they wanted something more aggressive but were difficult fitting them to the rim. I suggested a long lasting aggressive tire in the $175 to $200 range. I bet 2 minutes after I walked out he completely forgot the conversation we had.
