hi, im new to the forum and was wondering if i can get everyone's help. i have an 08 silverado extended cab 4x4 and am looking to upgrade my wheels and tires plus add a leveling kit. which kit would you guys recommend? also, im looking to run 20inch eagle alloy 064 wheels with 33" Toyo Mud Terrains, would this be possible? if not, what backspacing and offset should i look for in a set of wheels? what is the largest size of tire i can run? appreciate everyone's help!
