These are off of a 2012 Ram 1500 and I believe match the stock dimensions. When I bought the truck, it had 2" spacers because of the fender flares the previous owner put on. I didn't want the spacers but I wanted the look so I bought new wheels with the correct offset. These wheels are in great shape. They are 17x9 and can handle up to 37" tires as noted on the rim.
