I have a 2019 Z71 RST with a 2.5" level and 20x9 0 offset mayhem wheels. I had 285 55 20 AMP Attack pro on there and no issues at all. I replaced them today with 275 65 20 Cooper discoverer AT/3 XLT today and had to minor trim the mudflap on the front. Had a small amount of rubbing at full lock in reverse.
