Maybe...I have plugged tires for 25 years on over 86 cars and have never had one blow, leak or be a problem. It's all in a proper prep and installation.
There's also no need to remove a tire to patch a nail hole when a better method is a tire plug kit available at any parts store.
I pray no one takes the statement above and runs with it. There's no way I'd take a plug over a patch on any tire ESPECIALLY not a high performance tire/car!
Glad you all got this squared away and hopefully the buyer learned a lesson in communication.
