Most tire repair places won't dismount the tire and inspect, patch, and then plug. They'll simply plug the hole from the outside and fill with air. As far as I am concerned, that's too much of a risk. If you cannot see the damage inside, how do you know what's going on in there? That being said, I have NO problem plugging/patching a tire if it's done correctly. Especially if I JUST bought 4 new tires!
As with any decision involving risk, only you can determine what risk you are willing to undertake. How much is your life and/or property worth?? YMMV!
