I have no idea whether it would damage anything, but I personally wouldn't use anything that alters the seating of the tire. They just look like a bit of ricey dress up (bit rich coming from someone who just vinyl-wrapped his roof). In all seriousness though, you curb those and they could crack or scuff and it's still going to be as visible as scuffing rims. I don't see the point of them at all.
