Well I am new here and this is my first post, wish it were a better topic. Here is the situation. Just bought a 2010 Z71 Silverado and took it to to Allen Tire Co. to have AMP Research Electric Steps put on. While there the manager says you ought to put a leveling kit on it and I said yeah that is something I wanted to do anyway. They do that then start showing me some sweet wheels, BMF Novakanes 20" wheels and some Toyo M/T 33" tires which he guaranteed me would fit. Long story short they didn't and he talks me into cutting away some plastic and then sawing away some metal. I finally can't stand it anymore and tell him to stop and take everything off the truck. Even after cutting the 33" Toyos were rubbing on tight turn and I do not want any rub issues at all. Now they are suggesting a less aggressive tire the Nitto Terra Grapplers along with the BMF 20" wheels. I am still in shock with a truck that has 50 miles on it. I am back home with my original tires and wheels on, the leveling kit and my steps. The guy was surprised the 33" didn't fit saying he has done it before. Please give me your thoughts on why they rubbed so bad and what tire you think will work. I don't like the look of 20" wheels with smaller sidewall tires it's too "street" for me. Should I go with a different wheel in 18"? or should I try the Nitto's with the 20's? Does anyone have this same truck and tried to get 33's on it? Help!!
