Everyone here will tell you not to do it..........except me. I've had so many nails in my life, and I've plugged all of them, cars bikes, trailers. Never had one fail yet.
Of course dealers will tell you no, no money in telling you to plug it.
The odds of it suddenly failing and causing a wreck are no worse than a bird flying in your eye and blinding you.
Any members that have actually had either of these happen, feel free to tell us.
The plug might even be less immune to fail than the rest of the tire.
I use the truck plug kit with the black sticky noodles, and the oversize needle thingy. I even drill the hole larger to get it to go in.
When I drove a tow truck we did this all the time to the tow truck's tires.
Just not in the side wall, has to be in the tread.
If you die though, that's on you for listening to me.
