Recently purchased a 2013 f150 fx4 supercrew. Looking to do some rim and tire upgrades. Currently have 17” rims with 265/70R17 tires. I am going to put a "rough country" leveling kit on. I was wondering what the biggest rim and tire size I could go with without having to deal with rubbing or any fender issues. I was leaning towards a 33 on a 20x9 but Any information, suggestions would be appreciated. Thanks!
