I was wondering if i could clear 315/70R17 with 4" lift and 1" wheel spacers on my 02 tj? I don't do any serious rock crawling, but it does go through lots of mud and sand. I read that they are equivalent to a 34.4". Would i need a body lift or something else? I am currently running 33x12.50's and the front has plenty of clearance my biggest concern is the rear.
