A random wild thought on this tyre removal problem with CMP rims.
I think I might have read somewhere that during the war, when natural rubber sources dried up, synthetic rubber development got a huge boost. The story goes that a number of serious problems with the synthetic rubber quickly became evident, to the point that all synthetic tyres had a red patch added to the sidewall to identify them to be be inspected regularly.
If there is any truth to that story, has anyone ever noticed if it is these old synthetic tyres that are giving removal problems today, old natural rubber tyres, or does it make no difference at all?
