How would I go about putting BBs inside the tire? I'm guessing they won't fit through the valve stem, so would I have to pop a bead?
Is the noise of BBs falling when coming to a stop very loud? If so, that isn't acceptable to me. Perhaps the hub of the wheel could have some foam attached, or some spray in latex or something to dampen the noise.
The antifreeze idea sounds even better though. No noise, and it's cheap. Could probably fit it through a valve easily too. Any drawbacks to using antifreeze instead of BBs or other round objects?
