First puncture

The rear left tyre suffered a puncture after a stray hard spring pierced through the inner side wall. I was hearing a weird spring sound from the left side during night drive (very silent) Thought it was from the rear brake drum and wanted to check it myself and removed the rear tyre. Then i found this stuck to the tyre:

The nearby local tire repair guy fixed the puncture, but its loosing pressure rather quickly nowadays.

It was the first puncture for the Michelins after completing one year and 5k kms.
