Pokey, Correct me if I am wrong as it has been two years since I had some allied wheels in my hands but don't the allied's outer ring have a contour on the inside to help keep the tire pinched in place.
If so you may want to just leave the stock ring.
I will have to take a look. I havent had the need to break one down and I got them with the tires on already. I was just wondering since I like the look of some of the alum. rings
