16x8 smoothies brand new

Have a brand new set of series 12 16x8 smoothies from wheel vintiques .They have 5 on 5 and 5 on 5 1/2 bolt pattern with 4.5 backspacing. Only opened one box to see if they would fit but they won't. So they are up for sale.
Will trade for a new set of 15x8 or 15x7 series 12 smoothie with 5 on 5 1/2 bolt pattern but 5 inch backspacing.
