I was positive you guys were wrong but I just went and measured my 19" Matt Black Fpv Copies and they're 9 inches wide! I have looked at the wheels and thought they looked fat, especially from a distance, now I know why. Even though I only have 245's on them they are still a lot fatter due to being stretched over 9 inch rims, I would've bought 275's for the rear if I had of known that. I measured the genuine Dark Argents on my BF Typhoon a few years ago and they were 8.5 inches wide.
