The ad was for wheels and tires, but have been sold.
It depends on how concerned you are about cracking the paint when you roll the lips but you can do it by hand and/or with a rag wrapped around a 2x4 prying against the tire. I know it doesn't sound good, but I just went back with a little touch up paint on the underside of the fender (where you couldn't really see it anyways) and I was fine with that. As I understand it, even rolling the fenders with the roller tool still cracks the paint. If you are worried about your paint then I would recommend against it. Otherwise roll away and enjoy the results.
