We just redid tires and tubes during the condition inspection.
Replaced the old with brand new Michelin Airstop tubes, just purchased from ACS with date of manufacture listed as "MAI-2017"
We had a hard time getting them to take air, and when we tried to remove the valve core both cores were stuck firmly in the valve stem and came apart during removal:
With some difficulty we were able to remove the remaining piece of the cores using the reverse thread part of the tool.
Has anyone else experienced similar issues?
