Question on Wheels/Tires

Hey Guys, I'm shopping wheels/tires....I want to keep my front mudflaps and not looking for a bunch of rubbing. Am I good with this setup at +20 on a 285/60/20? I've been wading through all the posts, but I think its information overload at this point! Any info/advice is greatly appreciated! I'm also not completely sold on 20's....18's are always an option as well...This setup is for a 2018 CM that will have a 3/1 lift/level on it. Thanks!

 

You should be good. I'm running a 285/70/18 which is labeled as a 34x11.5 with the front flaps. I did have to push the front fender liner forward and drill new holes. I also flattened the mudflap as much as possible and redrilled a hole for the flap.
