In a previous post, "Jeep Wrangler Wheels and Tires", we discussed using 17x9" aftermarket wheels with -12mm offset, which is about 4.5" backspacing on a Jeep Wrangler. That sizing, for many people, is the magic combination to fit 33" or 35" tires on the Jeep JK. I was in that same mindset, but when I saw the new Method Roost wheels we're getting in, I knew I had to have them!
The Method Roost for the Jeep JK is available in a black or bronze finish. The bronze option only comes in one fitment, 17x8.5" ET 0. That works out to about a 4.75" backspacing, which is about a quarter-inch less inside clearance, and it's a half-inch narrower wheel, too. This means the tire will pull in toward the shocks about another 1/4". That's 1/2" total less clearance to the sway bar, control arms, shocks and inner fender wells. Initially, I was concerned about the clearance for my 315/70R17 Goodyear Wrangler DuraTrac tires with 3" of lift and only 4.75" backspacing on the wheels. But I was pleasantly surprised when I got them installed and they fit very well, and they look great! They even had room to articulate the suspension, which was my main concern.
My factory fenders are cut back like flat fenders to provide more clearance, but if you have rubbing issues and don't want to cut or replace the fenders, you can always put a bigger bump stop on the suspension to prevent the tires from flexing up into the fenders. This would likely be necessary to articulate in this way with factory fenders. Limiting straps are another option to limit suspension travel.
