I'd love to put a set of Sailuns on my Sundance 3300CK, but the trailer is rated for ST235/80R16 tires, and I don't think Sailun makes that size (or I can't find them if they do). I'm hesitant to go with the higher pressure 235/85s, because I'm not sure my rims are rated for those (and I can't find a PSI rating on the inside of the wheels). It looks like my best options are Goodyear Marathons or Maxxis M8008s. Any recommendations (between those two or any others)?
