Regardless of the trailer you're towing your truck would no longer be able to carry it's full load capacity with those rims. Your GVWR would be reduced to the combined weight rating of your wheels AND only then if you could load all four wheels equally (which is highly unlikely) OEM rims would be more than 25% of the trucks GVWR (about where you're at) which would allow for situations such as towing a 5th wheel where MORE weight is carried on the rear of the truck. Best when wheels match 1/2 of the axle ratings of the axles they're mounted on.
