The 185/80-13 is a great trailer tire option. It measures 24.4" diameter x 7.2" wide so as long as you have clearance for this new size it will work well. We recommend at least 3" from the fender and 1" from the frame. If you have enough room then I recommend the Loadstar ST185/80D13 Bias Trailer Tire with 13" Galvanized Wheel part # AM3S334 which has a galvanized wheel that works great on boat trailers.
