If you dont plan on lifting the truck get a positive offset wheel. Stay away from the negative because it will stick out and not let you fit as big of tire as you can go. If you are going with 20" wheels I say 305/55R20 or 285/60R20. The 305's might rub.
What size wheel do you want?

Pretty sure gonna need a levelling kit to fit 18's on an NBS truck.
