This chap was performing some maintenance or repairs on the tyre of this engine. I’m not sure what the tyre is actually made of – I know that they can have solid rubber tyres, but this one looked to be laminated in some way and some of it peeled off in a layer as I observed. Perhaps that’s just the way rubber tyres of this sort are constructed, or perhaps it was made of some other material?
