Personally, I like them the way they came from the factory. Done stock, they just seem to look "right" to me. If I understand your description of white trim, you have a Deluxe cab (painted grill, bumpers and hubcaps vs. Custom cab with chrome grill, bumpers and hubcaps) and not a two-tone truck.
Truck specification sheets for 1959 list black wheels for all single-color cabs and primary body color for all two-tone cabs. See page 32 of 83 for chart:

By the way, at least in 1959, stepside and Deluxe Fleetside trucks had Chevrolet painted in white (Bombay Ivory) letters on the tailgate. Custom cab Fleetside truck tailgate lettering was body color.
