Spacers shouldn't be needed. The 17"s have an offset that puts them way out to the fenders but the spokes come back in. Spacers would possibly have them looking funny and rubbing the fender even more. Though they shouldn't be needed for this. I hope. And the 16"s have a similar offset but normal spokes.
