Is this puncture too big to repair ?

[Audicfc]

Is it possible to repair or will i need a new tyre ? The tyre is only 2 months old on the rear it is a gy eagle f1asy 6 225/40/18
Looks like really strong solid glass almost metal feeling not got a clue what it is exactly, could feel something stuck in tyre then sounded like it broke off then was left with this in tyre when i got home and was completely flat within 30 mins

Anyone any ideas what it could be ? Looks like it has bits of green through it aswell

Looks quite a rough cut

Yeah that's too wide imho, a nail, screw yeah but that's a long strip, new tyre if the pics are as I believe.

Agreed , that tyre is toast I’m afraid. No rubber bung going to fix that !

Ok thanks, just one of they things you need to deal with i guess i just wish it was on the worn front tyres instead

Typical bad luck eh ! Feel your pain. If you’re in the uk take a look at

Got new tyre fitted today at costco, turns out it was a key that punctured my tyre i would never have expected that to be the cause of it
