Hi i run 15x10's with a 4" back spacing on mine with 33's and have no drama but to run 35 i will have to wind the stopper bolts out a touch hence less off a turning circle
i trided my 33's on my standard rims
and they rubed on the front spring but using the 10"rim makes the tyre into a squarer profile insted of a hudge balloon I was also told that running a 10" rim will chew wheelbearings out quickly but my rims have been on two cj's and have never had any wheel bearing probs at all
hope this helps
