One of my concerns with installing 33" tires was clearance. Stock Wrangler Moab wheels have 6.25" of backspacing. I found that the front tires would rub on the sway bar at full steering lock. I removed the steering stops and shimmed them enough to restore clearance. However, that increases the turning circle by about 5 feet. So, I ordered sets of wheel spacers for each axle. High end, billet based spacers. Expensive, but they are stronger than the wheels themselves and set the backspacing at 4". Once I get these installed (over next weekend, I'll reset the steering stops to where they were originally too). Also, a more robust steering damper will be installed as well. The new tires are heavier and the stock damper is marginal at best. Besides, I found some minor oil weeping on the damper, meaning that that shaft seal is worn. You see, when something wears out on a Jeep, it's a great excuse to upgrade. Even though the damper is covered by the warranty, it's still not up to the task of controlling the bigger, heavier tires as well as I would like.
Despite a rough winter and some very muddy off road trails, the two year old JK cleans up like it just rolled off of the showroom floor. However, within a week, it'll be a muddy mess again....
