I'll be lifting my XJ in a few weeks, and I'm trying to decide on a tire size (and lift, for that matter... either RE 3.5in Superflex or 4.5in sf). I can't decide if I should run 31s or 32s. I wont be able to afford a regear for a while, and I do a lot of highway driving. I know that 31s aren't too bad with 3.55s, but I don't know how 32s will be... What do you guys think?
