Air in tires adding to weight?

Is there a rule you can reference that verifies this claim?

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).

I didn't see it as being illegal. However, keeping it from escaping is not easy. And to get much lift... well, let's just say that you'd probably either have a structural failure or negate all of the lifting capability by adding strength to have any chance.

There are plently of ways to lose weight.
I whould try cutting holes or trinagles in your bot if possibale.
If we can see a pic of if we might be able to give some ideas.
