Every time this thread comes up I also re-think it. I think the pictures posted by the members above show that they don't look bad and actually, with an aggressive tire, they can look good, e.g. @TimHerald. I think with a more plain tire, they draw the eye a bit too much but still, they don't look bad.
The problem is it looks SO good without them.
