The tire size you're looking at now is approximately 31"s, so they are a safe size. The next issue is rim offset. If you're going with 17" rims off a Ram the rims should have a positive offset, but the wheel adapters will push out the rims and add leverage on the bearings. In my original configuration, I had 32s on deep dish aluminum 15" American Racing rims. The bearings didn't like it too much, but I was able to get a set last me about four years, so long as I kept them out of the mud. The others….well lets say I love to go mudding and they didn't.
Anyway, I hated replacing bearings. So, I swapped out the front axle assembly and put tons under it and now it rides on 41.5" Pitbull Rockers….oh, and I stuck a Cummins in it too.

As to the body mount. If you're talking about the metal support thats welded to the floorboard, just behind the front tire. This is a known rust out spot. If you look at the mount, it's right behind the tire, right where tire spray goes. Theres a rectangular hole where the spray can get into and that cavity will fill up with dirt and crud, and that will eventually lead to rusting. I had this problem on my Dakota, and eventually the mount failed. In my case, I decided to replace the entire cab as the rockers and part of the floor were also rusted out (The PO came from Michigan)
In your case, a body swap will be a bit more extensive as you'd be replacing an entire SUV body, if you went that route. As far as I know, there isn't a reproduction or replacement component. You might try someplace like Rock Auto, but I doubt you'll find what you need. The only other option is to cut out what you need from a wreck or fab a new one out of heavy gauge sheet steel. In any case, this will be a rather large job. You should also look at the opposite side and consider replacing that side as well because it won't be too far behind in condition.
And as a public service announcement to you and everyone reading this, if you want that mount to last longer, fill in that rectangular hole behind the front tire, to keep the crud out, especially if you live where the roads are salted during the winter. Maybe apply a coat of a rust inhibitor like POR15, Fluid Film, or even used oil.
