Guys would like your insight on this please...I have right now LT255 75 R17 MT tires...
i got a RE Budget lift put on this weekend...To get a different size tire that you would
notice a difference what would you suggest...Keeping in mind i drive 2012 Wrangler Unlimited...

 

Many of us have agonized over this decision (countless threads about it). I went from a 255 to a 285 and I regret it (barely noticeable). I should have gone right for 305s or 315s (approx 34" - 35", but usually less than that when mounted).

My .02c

 

I went with 305/70/17 GY mtr's . they measure 34 inches mounted. I had to trim the front splash shield a little and replace he spare tire carrier to fit the 34 inch tire. I have the Tera flex leveling kit on also.
