I'v scrolled endlessly through the forums and haven't seen a definitive answer to the question below... Will 275/65/R20 BF Goodrich KO2's fit on a 2018 GMC Sierra 1500 with a 2.5 Rough Country Lift OR MotoFab 3" Front 2"rear Leveling Kit w/ UCAs - the kicker... on Stock 20x9 Snowflake Wheels? In my search I have found it does in fact work as long as you replace the UCAs, Minor rubbing on the inside of the fender looks to be the biggest issue. Some say spacers some say no spacers, super lost! Please advise!
