I took off the wheel with the tyre problem. easier to clean it and get the Evostick on to it. I was somewhat dumbfounded to find that the bearing at the wheel centre was a Japanese NGK bearing, instead of the expected cheap Chinese version! Maybe the bandsaw was made in Taiwan?
Just as a matter of interest Solent Tools do rubber tyres for the Draper BS355A bandsaw (the identical saw to mine, which may indeed be a Draper!). Not exactly cheap, but not too bad (about £11 for one up to about £27 for 3). So for anyone not wanting to fiddle with DIY versions, then they can get tyres to fit.
I Googled granulated cork rubber sheet and indeed it is quite common. Seemed quite expensive for pieces long enough to produce a tyre (needs to be about 570 mm long).
