My current set up is a set of BF Goodrich Mud Terrain T/A's, L255/75/R17, mounted on Jeep Rubicon Moab Rims from a 2007 Jeep Wrangler Rubicon. These are 32" tires mounted on 17" rims and I have to run the 1.5" Spidertrax spacers in order for the rim to clear the brakes. I also have the 2.25" Rocky Road lift to allow enough room to run a 32" tire inside the wheel well. There was some wheel well (plastic parts) that needed trimming and the pinch weld has to be rolled over a little or it will come in contact with the outside edge of the tire.
