I'm not sure, since it punctured the inner tread rather than the thick outer tread. I don't see any creasing, which is indication of a problem/bad tire if creasing is present. I would ask a good tire shop. The Delinte D8s I have are not marketed as RFTs but they are (not really sure how/why they are marketed as such); I got a thick deformed nail on the very outer tread about 3" to the right of your location in the rear right tire about 8 months ago. It was patched by my local tire shop that had installed my 22s. The tire has not lost air or had any issues whatsoever since then. It only cost me $20.
