Antique wheel/tire question


Recommended Posts

There is an old photo on another site that caught my attention with this detail. How is such a tire inflated with the multiple valve stems? Are these all active or are most of them dummy stems? Probably not but then would that mean there are multiple chambers which need to be inflated and matched for psi? Would this obviously require special tubes? I know there has to be an obvious answer...I've just not noticed this before. It does seem like the one on the bottom may have a cap on it...Here's a close-up of a similar Pope-Toledo from a dealer. Thanks!

There is only one valve stem near the bottom in the photo.  The other fasteners help hold the clincher tire in position on the rim.  Here is an illustration from an old Dyke's manual:
