I have 14x7 ITP T-7 beadlock, 4+3 offset, 4/156 bolt pattern with 26x9x14 front and 26x11x14 rear maxis bighornes. Prior to my lift, they slightly rubbed on occasion but with no concern. The passenger rear comes real close to the motor mount. I think this is as big as you can go on stock rzr with no wheel spacers.
