I have all sorts. I bet the tires on the 3500# axle are still 30" tall. Tandem 3500# axles are spaced about 3ft apart, center to center. I'm betting it would fit fine... Wheel size, offset, etc is probably the bigger issue.
I just replaced all the tires on my trailer including the spare(5), for $440 installed with new valve stems. 225/75/15 load range E. I told the guys that they needed a punch card like coffee shops use, after 12 tires I have bought there this year I should be getting a free one!
Thanks guys a lot.
Tires on it are 8.5-15..they look about 30" or so (def bigger than like a 235). No fenders currently either and remember seeing about 3"or so between them. When I get home I'll post some picks. Happy eating everyone! Food is smelling good (my son is cooking and being culinary chef, whew!)
