Weight should be OK. Rear tractor tire width may be too wide, depending on the trailer style and the tractor wheel adjustment. If it is a car hauler and a tricycle tractor, is there a place for the front wheel?
You probably know this already, but rear wheel hubs are often not in the center vertically. You can often make a tractor either wider or narrower, than otherwise capable, by swapping wheels to the opposite side, but still keeping the tread going the right direction. The inside of the wheel becomes the outside, not like changing car wheels from side to side.
Tractordata.com says rear wheel tread on early models is 56 to 84 inches. Later ones may go wider, but close to the same on the narrow side. I think that is usually measured from the center of the tread.
