looking for wheels (beadlocks) for my rubicon with 2-1/2 lift and my coopers 37 x 13.5 x 17 tires, want max flex without having to lift any higher if possible. from what I can find 4.5 to 4.75 OS looks like it is the best for not hitting the outside flares and should only need to form back plastic and remove lower bumper guard. Any help would be helpful, Thanks
