I'm running 35x11.5r17 (measures about 34" when mounted) on +30 RTR EVO 6 wheels. Crash bars are still in place.
*Same tires also worked when I had them on the BD steelies.
@Aonarch Looks awesome. I'm getting the exact same wheels installed on Iconic Silver today. Are you staying with the RTR centercaps or going for bronco overlays?
The local shop here will actual do the tire unmount/remount with powder coat for around $600. They ran specials last year for a set of 4 for $450. That at least is a data point to use.
