I do have another tire (Serfas Seca) but I'd rather use the current (GP 4000). the sidewalls seemed not more damaged than before. With the delivery times of PBK it would be tragic if these blow ups somehow have damaged the tire too.

Anyway, I'm going to sleep now and tomorrow with a fresh mind will give it one last even more careful try.

If it blows up again, I'm going to the LBS.

Thanks again.
