gash in tire

[retcav1sg]

Tire is brand new...Michelin Diamaris and got a gash in one of the raised center channels. The inside of the tire is fine...no evidence of the gash, not even a raised area where the gash looked like it trie to come through. What to do...leave it alone, professional patch to reinforce inside area opposite the gash or god forbid...trash the tire?

Thanks in advance for any responses

Sounds terminal to me, I'd pitch it.
