Plugs have historically failed in both automotive and motorcycle applications. I investigate such claims of damage for AAA. The problem is that a tech or a no tech can never really no the shape and extent of damage. It may look like an ordinary nail, but depending on how the tire picked up the object, it may have ahd some lateral damage as well. In order for a plug to be an "accepted" repair, the hole must be reamed to the exact circumference required by plug manufacturer, and must also be done at the angle of entry into tire. Without the proper technique, and the stars lining up, a plug is at risk of failure. Also, if not trimmed properly after installation, rubber compound can grip hot asphalt and be pulled out of the tire. Trim too much and it can be pushed into tire.
If I were you, I would carry a plug to be used ONLY to get you SAFELY to a shop and let an expert determine the original cause of failure and what course should be taken. Personally, I would replace a tire even if it was just driven out of showroom. A tire is only as strong as its weakest area. you only have a few inches of rubber on the ground at any moment. Your worth the cost of a new tire!!!!!
