285/60/20 BFG K02 absolutely no issues. I added the larger GM splash guard as well, they fit a bit larger than the originals but still clear. I travel some gravel roads and the K02's will certainly throw some rocks. I feel the guards, especially the larger fronts help keep them off the rockers (and for the guys that keep asking about the exhaust tips mask and plastidip in place, 6 months no issues).
