Hey guys. I have a 2015 z71 offroad and want to level as high as possible and run as big and fat of tire i can on stock 20 inch wheels. I also want to put fender flare on, hence the fat tire. Can anyone tell me if i can run a 33x12.5x20 tire with just leveling or would that require a lift, which i don't really want to do. I've tried the different websites and things just get more co fusing.
