The best tube for size 33x5 available anywhere in the world.

We made this inner tube at the request of Richards Bros. in Cardiff (wire wheel builders since 1937) who explained that no one makes a correct dimensioned tube to fit a 33x5 tyre, which meant everything they fitted was a multisized labelled "bodge", which would be either too large or too small diameter for the tyre. Because Blockley was making a 33x5 tyre we realised we needed to make a proper dimensioned tube, nice and thick, made from butyl with a nickel plated 75mm length metal stem in the "on centre" position for straight sided (and beaded edge) wheel rims. This is the only tube made that fits a 33x5 tyre as it should be, along with the usual Blockley quality to suit.
