I have a 2006 Triton TR-21x. I bought the boat in 2010 with brand new Goodyear Marathons 215/75/14. Those tires have been great and I still have them...going on 9th season. I do not travel much, am going to start making some 2 - 3 hour trips to different lakes soon. What recommendations do you have for tires and where to get them?
