Hi All: I am looking to do a wheel/rubber change out on my 2017 NV3500 SL. I want to go to an all black wheel and a more aggressive A/T type wheel. I have just started to research this topic and before I go see wheel/tire people I would like to educate myself a bit more. I have included, what I hope is accurate, a listing of factory wheel/tire specs. My confusion lies in the wheel diameter and offset. I want to stay with the 17" wheel size but does anyone know how wide a rim I can go to or how much offset (+/-) can be utilized before any rubbing occurs? Thanks for all your help.
