Suicidal squirrels seem to be "fairly common," in my experience. I've had two in the last seven years -- one I ran over, the other bonked his nose into my rim and then skittered away with what I expect was a very sore nose. If "unusual wheel configurations" encourage them to run through and get caught in the spokes, then I'd sure rather be running 36 spoke wheels :-)
