I did have some rubbing... See picture... This happened when I would back up my driveway. Rubbing on the drivers side. I trimmed the plastic and tighten the screws (this weekend)... I haven't had any additional rubbing as of yet.
Here is my 2017 Sierra Denali with leveling on 285/55/22 G's. No trimming. Rubs a bit when backing up my driveway. I might do a bit of trimming. I haven't decided yet. Love the look though.
