Strength of OEM Aluminum Wheels?

Naxja,
Does anyone have any first hand experience with the aluminum oem wheels that came on XJs ever failing when on rocks. And I mean rock crawling and getting the edge of the wheel on a rock and the weight of the jeep bending or cracking the wheel?
More and more of the trails I am running here around VA,NC,WV, and TN have bulky rocks that make my 33s look pathetic and after wheeling I will find that my wheels have a lot of scratches on them from grinding against rocks. I love the way my OEM wheels look and changing to steel wheels with rock rings isn't on my important to do list.

BTW here is what I am wheeling on



Here you can see how the middle kind of bubbles outward.


For anyone that doesn't know there is a ton of backspacing on these wheels and the part of the wheel that sticks out the furthest is right in the middle where the lugs are.
I was kind of figuring the side of the wheel you see when on the jeep should be very strong given all of the material that is right there but I am worried about the inside lip on the backside being bent pretty easily?

Any advice I can get would help. This is my DD if that changes anything. Has anyone wheeled these or other Aluminum OEM wheels before and abused them to a point of bending/failure?

Nick, I've been wheeling on Aluminum wheels for years.
They get rock rash, and I've even left a bit of metal here and there along the trail, but I have never had one bend or break.

'Course I only do light wheeling where I drive it like I expect it to get me home (which it does), not any extreme wheeling where you expect to have a trailer to get it home.

On my 2001 I run the factory aluminum wheels off my 1985 XJ (the bullet hole style) and, in Tennessee, Kentucky, and Alabama, run the same type of trails as you.

I second Ron, they've got rash but never failed me. I say run 'em.
