For the archive, here is Van's reply re wrong tube.
"Those are the only tubes we have for the 5.00 x 5s (I presume they are
marked for 5.00x5s?) and they will work OK, if not ideally. When inflated the
tube will force the valve stem towards the wheel rim. We used get tubes with
valve stems with a double bend that avoided this problem, but Desser (the
tube mfr) tell us that those stems are no longer manufactured, and
Cleveland have not moved the hole in the wheel further inboard so it works
better with the available tubes. See attached pic.
