84 Blazer 2wd tire size??

[2wd82]

I have an 83 Blazer S10 2wd completely stock and I'm looking to go to a larger tire from the stock 205/75R15.  I was looking at either a 30x9.5R15 or a 235/75R15.  I konw that they are incredibly close in size and was wondering if anyone knew if I could fit them with no to MINNIMAL rubbing.  I have got very mixed answers on this and would really like to hear from someone who has tryed to run this size tire on this truck before.  THANKS FOR ANY HELP YOU CAN PROVIDE!!!!!!

you should be able to get a 235 75 under it no problem. my 94 s15 came with 235 74 15 but my friends 2wd 96 came with a little smaller he moved up to 235's and rubbed just a bit up front, but we took a small hammer and dented in his fender well and it stopped.
