wheel question

[CountryBoy704]

So I'm looking at a great deal on some lightly used 33" boggers. Would an 8 or 10 inch wide wheel do better off-road? (I'll have stock wheels/tires for normal driving) I know people do the 8" width and 4" backspace a lot and that works well but if I got a 10" wide wheel would I have to compensate for that with more than 4" backspacing? I also think the huge-ass lugs of the boggers might need more than normal anyways to avoid rubbing the rad arm? - mine are stock btw
Thanks - CC

8" would be better off road. it will hold the bead better at a lower psi.

What's the width of the tires? (33 x ??.??)
