I'm running the MB TKO 17x8.5 with 33's now. There was so much rubbing that I had to cut out the rear seat heater hoses and beat the pinch weld as flat as I could. They also took out both my TPMS receivers. Other than that, they protect the valve stem much better than the Pintlers did, and the rims hold up to abuse much better so I don't knock chunks off the bead. As I have discussed in other threads, the XK-version Pintlers had the wrong backspace (5.75") and were bending the tie rods at full-droop and full-lock. The JK Pintlers backspace (5.25" was it Matt?) should rub a lot less, but again, are not really for trail use IMHO. I would say that 8.5" wide with 5.25" backspace is about optimum.
