by the way
did anyone have the issue where the tread rubber became much longer than the channel when trying to put it back in after a clean?
each of mine gained two inches and I had to cut them down
bizarre
or spooky Morgan magic
When you pull the rubber strips they tend to stretch a little and the cross sectional geometry tends to shrink (Poisson’s ratio). There is also a bit of memory effect to their recovery. However it is possible to feed the stretched length back in but you need to keep it under compression in the length direction and use some lubricant.
A point probably worth mentioning. I don’t know exactly what type of synthetic rubber the strips are made from. This may not be relevant but certain synthetic polymers do not react well when they come into contact with petroleum lubricants (Vaseline for instance). They can swell and degrade with time.
