I personally don't think the load rating of the rims matter, in the sense that you do not need a rim with a higher rating if you move to a larger rim. You're not changing the weight of the load -- it's the same trailer. So if the old rims had a weight rating of 1870 lbs, the load rating of the new ones on which the heavier tires are mounted doesn't have to be any higher.

WHAT DOES MATTER, however, is that the new rims are rated to handle higher air pressure. In trailer tires, that typically comes with larger rims, since higher PSI is what gets the higher load rating, but it makes sense to verify.

In my load range E tires, I run at 65 psi cold, which has proven to be a good balance between load support (e.g. no blow outs) and a relatively smooth ride in the camper.
