Rim and tire fitment question

I was kinda wondering if there was a way , without messing up the trim ring , to cut down a 15 x 7 ring to fit a 15 x 6 wheel. Cut around the inside , with something like a bead roller device.

Frank, these are the 2" rings I put on the 6" rims. A 2.5" would be better, but these work for me and the price was right.
