Uncut Bronco Tire Size

[cowmountain]

I have a '77 uncut bronco with stock suspension. The wheels are apparently 5.5" rims and my current tire size is 235/75/R15 which, I understand, is a 29" tire. I'd like to use this bronco for ranch trails which means that it's mostly going on dirt roads without major obstacles other than some ruts. If I keep the stock suspension what is the largest tire size that I can go to without cutting the fenders and without rubbing? Thanks.
