Plumber,
I looked at the specs of a GY marathon, 205/75-15. It is 27.1" dia.
The GY Cargo LT 225/70-15 is 27.4" dia. Approx 1/4" taller, of which only half ( 1/8" ) is a concern regarding vertical clearance to the fender well. This tire has 2470 lbs of capacity, which is just short of 10,000 pound for four of them.
Don't forget that if your trailer weighs lets say 9000 pounds, then approx 1170 pound is tongue weight, so that weight is not supported by the trailer axles. That is how the RV company gets away with installing tires that have a lower overall capacity than what the trailer GVWR is.
EDIT, I see Don was typing at the same time I was re tongue weight. Also, as Don says regarding LT's, I would add further they bring other advantages as well.
