Pneumatic tires are not pneumatics. (Blue box, [R71]).

The reason pneumatics are supposed to be empty when weighing (and all through inspection other than the power-on check) is for safety, so that something doesn't go totally haywire. Pneumatic tires don't have that problem.

Therefore, I can conclude that pneumatic tires, if deflated for inspection, must compete as inspected; i.e., deflated.

Oh, and Dr. Joe is right about air's lack of weight savings. Just trust me on this (other than: I was dealing with about 3 IWC air last summer).
