Cindy and I have been really happy with the Cooper STT Pros that we’ve been running on Moby and Rubicat for a while now and so it should be no surprised that we really wanted to run them on JET Li, our brand new 2018 Jeep JL Wrangler Rubicon Unlimited as well. Needless to say, we picked up a set in a 37×13.50 but the real question we needed to answer was what wheel to run them on. As luck would have it, KMC just came out with their all new XD231, Robby Gordon bead lock wheel and soon after we first saw them, we knew right away that they were going to be the wheels for us. Fortunately, they are available in a 17×8.5, come in a 5×5 bolt pattern and even have mounting holes big enough to fit the 14mm studs that now come on the JL. For our purposes, we were also happy to see that they came in a machined finish and have a nice, 4.75” of back spacing.
