You can do trailer tires even on a tandem axle. Its done all the time. Ive used Maxxis trailer tires on a tandem for a smaller Bass Cat. My brother has loaded them on a Cougar FTD trailer before as well. A lot of it has to do with the wheels in question…..are you in the 15″, 17″ or 18″ range? Ive got a set of Trailer King trailer tires that came on my 2015 Bass Cat trailer and they are doing fine. You can always call up to the factory and see what tires they are using now. Max pressure (cold psi) and make sure load range gets it taken care of. Other than that, happy hunting!96 Eyra/12 Mercury 175 Pro XS with 2015 single axle trailer2017 Victory Gunner
