Only if you change tires to a wider one. Using wider rims than specified lowers the weight rating of the tire itself.
Tire manufacturers publish specs for the tires that give the recommended width and also acceptable width with the note that it reduces the capacity. If you're close to capacity then it might not be a good move.

3/4 of an inch aint much. Shouldnt change the profile of the tire at all. Might want to measure your rear axle spacing to make sure you have enough room back there.

3/4 of an inch is enough to substantially change the weight capacity of a tire. That's why the tire manufacturers publish the specifications.

Don't guess about tire widths vs wheel width - check the tire manufacturers specs and get the actual rating. They may well allow a different size but might change the load rating.

I'll disagree with Weather Todd - 3/4" is about the most you can stretch a tire without serious risk. Yeah, people do it, but people also have tires break loose from the wheel in a sharp turn or have blowouts from extreme flex stress.

a 245mm tire is 9.5" wide. In this case going to an 8.5" wide rim will not change anything. How much would you care to wager on this?

The import fellas stretch a 205mm tire onto 10" wide wheels quite often. Now Im not recommending doing that BUT it can be done and they often share the road with you.

If you go to the wider wheels,it would be a great time to step up to a wider tire size. Higher load rating will give you a little more margin of safety.
Happy Glamping.

When I checked into replacing the steel wheels on my Meridian I found that there is a lug bolt length consideration. Apparently the aluminum wheels are a good bit thicker than steel wheels and the lug bolts may not be long enough to safely accommodate the added thickness. The truck tire shop I buy my tires from told me my front hubs "probably" had long enough lug bolts, but the rears do not. So I polished up those ugly old stainless wheel liners and moved on with life

The recommended rim width for my tires is 6.75 to 7.5 inches. That's for the 23580R22.5's
For larger 25580R22.5's it's 7.5 to 8.25 and 30570R22.5's it's 8.25 to 9 inches.
This is from Michelin's guide pdf.
If you are buying new tires as well, getting a size up will give you a much better load capacity. MH tires are run at or near capacity much of the time and I feel that is one of the biggest contributors to tire failures.
Happy Glamping.
