2018 Silverado 1500 LT Z71 crew cab short bed fitment questions

[2018Z71Texas]

I just purchased a new 2018 Silverado LT Z71 4wd crew cab short bed and am planning on putting the zone 4.5" lift kit on the truck with fox shocks. I love the look of deep dish rims and am leaning toward Hostile sprockets. I am wondering 2 things. 

 

1. if going with a 20x12 on 33 m/t and -44 offset, how much cutting would be involved to solve the rubbing issue and would those cuts be visible with the wheels mounted from the outside?

 

2. What is the meatiest size someone would recommend for the Hostiles on 33's without having to cut and without rubbing on the 4.5" lift?
