Before you rule out replacing those wheels you'll need to inspect the bead area very closely on your OEM rims; with the age our trailers have there is a corrosion pattern that weakens the flange where the bead seats.
Moisture is trapped where the rubber and the flange meet and pitting occurs along 8, 12, 16-inch arcs, the length looks like it depends on how long the trailer sat in one place so gravity had its say in how long rust undercutting was active. If it is just minor surface pitting a good scouring and some tough paint, if it became deep canyons eroded out (like I saw on one of my '73's) then new $50 steel rims may be called for.
And note: this is in addition to the general rule not to increase load rating on our old steel rims, say from C to E, as the metal itself can suffer failure from new stress points relayed from heavier sidewall force(s) of the new tires.
