It is relatively expensive, but most 8 lug trucks and motor homes with 16" wheels can step up to 19.5" wheels and tires. It gets you a 4500# single wheel rating, and a 4350# per wheel dual wheel rating. You can then buy good quality G rated 14 ply commercial truck tires for around $300 each, and leave the 16" tire blues behind. Doing just that to my Chevy 3500 Silverado right now. If you plan to keep your vehicle, it is worth it. The tires last much longer, and control heavy vehicles much better, for very little more than a super premium 16" tire. No matter what, you cannot make a 16" tire do what a 19.5" tire can do with ease.

Depending on the chassis/powertrain, you can get steel 19.5" x 6.75" 8 lug wheels that bolt on for less than $150 each. You can get aluminum for as little as $250 each. you don't need any adapters, they bolt right on.
