Maybe something to think about here:
On my old YJ I ran 10inch wheels for may years. I had front and rear lockers and beat the living crap out of it. I never once had any issues on-road or off-road with a 10 in tire.
That said the tires stuck out pretty far. I didn't mind it myself, but if you live in an area where cops bug you about flaps, they could be a problem. You could cover them with deeper flares, but I didn't. I didn't really get hassled, probably because I had a massive lift. BTW My tires were BFG MT's 33x12.5r15s.
The bad well as I mentioned before they stuck out of the fenders pretty far. i know you can take care of some of that with back spacing but not really or you will be rubbing under the Jeep.
The other bad is that when you are out wheeling, you will scrape the rims on rocks there is no protection they are out there.
With a 8 inch rim it gives you more sidewall and it will scrape before the rim does. By the time I sold my Jeep my rims look like I kept taking them to horrible tire installers.
I am running 8 inch now with 33x12x5r15. I actually like it better myself, but I am getting older and a little calmer.
So you could choose either but I think you will get less rim damage on a 8incher.
Not exactly what you are looking for but here is my BGFs with 33x12.5r15s on a 10 wheel. Keep in mind that is on a 6" lift.
Also a YJ ^^
Here is my TJ with 33x12.5r15s with 8" wheels:
If you look you can see that on the 10" the sidewall is almost flat, but it is more rounded on the 8" both sets of tires are the exact same size.
