I have to agree with docwra .. I think it would be ok. I've had tyres worn down on banded steel wheels so low that the metal braiding was sticking out like a worn toothbrush ( not used on public highways I'd like to be known ) and not even a slow puncture in that condition... If you are unsure about it still then you best have a new one for peace of mind but I know what I would do. Good luck
