I have an 08 Silverado 1500. I want a 6.5" lift from Zone. I was wondering if I would be able a 33" Toyo with either a 20x8.5" rim with 5.1" (10mm offset) or 20x8.5" with a 5.9". The guy installing my lift is concerned with the tire rubbing the control arm/ ball joint. Would I be okay to have him install it or not? Sorry if it's a noob question, I just got my Silverado and I'm only 20 and I've never done anything with trucks/lifts or anything before so it's a learning process. Thanks!
