Well, that would depend on what constitutes an "air filled (pneumatic) wheel". Do I require the hub? Does the inner tube alone count?

I realize I'm lawyering, but that's kind of the point of this discussion, no?

I would tend to agree with Tristan's view that using a balloon *may* not constitute a violation of the pneumatics rules, but its certainly a grey area.

For years, the pneumatics rules forbade pneumatic wheels without specifically calling out an exception, but teams USED pneumatic wheels. Nobody noticed that the way the rules were written forbade them, because nobody thought of a pneumatic tire as being a pneumatic device.
