this question has probably been posted before but i cant find an answer

i am looking at lifting my o5 titan. I have been reading about the prg kit and burtman's cornfed kit and talked to both of them burtman was not sure what tire i could fit and greg said that he has a 35/12.5 on his truck w/ 17" rim and aftermarket wheels. Im leaning toward the cornfed kit cause it has a little more lift and was wondering what size tires can fit (i have 18" stock wheels). Im open for suggestions!!
one guy i think on here said he had 325/60/18 and w/mini lift had no trouble, another person said 325/65/18 and he had no trouble, but another guy said he had to modify the inner fenderwell on his truck with the 65's.I really dont want to cut the truck. I wanted to do a mini lift and am not sure what i can fit so i was hoping you guyz would have some input of your trial and errors. If you could help me that would be great cause im in need of new tires
Thanks

I've got topguncustomz level. Virtually the same as PRG (goes on top of strut). Havent had any problems yet!! Cheaper. The offroad joint advised me I could go up to 325 60/65 18s (I have) with no problem. Dont have new wheels yet.

do tou have the 60 series or 65 series and what did you have to do to fit them remove mud flaps Etc?
