I agree that it has the "fingerprint" of a puncturing object, but...get yourself a spray bottle with a mixture of dishwashing liquid & water. Spray the entire tire & wheel and you'll find the leak. There are only four places from which it could be leaking:
1. Around a puncturing object (hope that it's in the tread, not the sidewall--a sidewall puncture means you have to buy a new tire)
2. Between the tire bead and rim (this can be reseated or sealed by the tire dealer if the bead is not ripped)
3. Around the valve stem or valve core (cheap repair)
4. Through a pourous aluminum wheel (can be sealed, but should be covered under warranty)
Hope that helps!
PS: I just pulled a screw out of the tread of my LF...thankfully, it wasn't deep enough to aspirate the tire. These pavement-roller tires do seem to find everything!
