I disagree with Ronzi. Your wheels are not supposed to be this way.

My wheels used to be smooth on the inside. Then I had an accident and the rims needed to be straightened (fronts only). Now the inside surface is rough as you are describing (whereas my rear wheels are still smooth on the inside.) It matters because it IS noticeable -well, not to people who aren't perfectionists maybe, but it is annoying. True, it doesn't affect anything, but neither does a rip in the seat. It's just not correct.

I suppose your wheels have been refinished in some way. If any one else is experienced in the process of mending wheels, please post. I'd like to know as well.
