The best I can describe them is finned. They are 14" wheels and I dont know how wide they are, maybe around 5". Not attractive in the slightest. I am getting rid of mine and going with the 15"x7" 10 hole wheels in a couple weeks.
i have one, its a anchor for an Easy-up.....i gave up on trying to get rid of it...maybe ill get it powder coated to see if it looks .1% decent, just for kicks!
