450/500x17/18 Inner Tube

A rubber valve stem, extra thick and correctly dimensioned Blockley butyl inner tube. Nothing available elsewhere is this good. This tube fits the range 450 and 500x18, and not one of your usual multi sized written on tubes offered elsewhere. All Blockley tubes come as standard with metal caps (not plastic) ones.

(£27.60 inc. vat)


The Blockley range of inner tubes, produced on our own Blockley tooling, with a generous thickness, are unlike anything else available. Because there was nothing available that we liked, we embarked on making our own Blockley superior inner tubes. Not only are they made using the best material Butyl, but they are also thicker (as tubes were prewar) than anything else available.  We manufacture this inner tube only for the 450 to 500x18 tyre sizes.  We are unlike the big Classic suppliers who like having one tube with myriad widths and diameters listed on them.  And by supplying all Blockley tyres and tubes direct to the end user or restorer, and avoiding these Classic tyre Wholesaler companies, it means the best tubes in the world cost little more and often less than the cheaper made alternatives that these wholesalers supply. And don't forget to fit the Blockley rim bands.
