Schwalbe One Problem?

What an informative and helpful reply form Schwalbe. I think i will contact them about the repeated instance of premature sidewall cracks and miss-shapen marathon tyres.

I have used the previous version of the Schwalbe One for years and the chafer always starts unravelling as in the second photo. This starts happening earlier if you run your tyres at lower pressure.

Not a problem as long as enough chafer remains to prevent the casing from directly touching the rim at the contact patch over big bumps. Pull the loose threads off by yanking them tangentially to the rim to avoid causing more unravelling.

Agreed - but its better to cut the threads with scissors than to yank at them, as yanking can just pull off more of the thread that was still stuck to the sidewall, thus accelerating the generation of future thread wisps.
