Of course, for them it's a CYA type thing.
I have a couple of tires that have had plugs in them for years. I must admit that if I use a plug on a steering tire, I have it patched later.
Why do I have so many flats you ask? In my little Toyota, I go places where I shouldn't and many places I go there are very sharp rocks, and plugs have saved me many times, and without having to remove the wheel from the vehicle while the little truck sits on steep slope.
I've only plugged one tire on the RV, about three years ago, and it still holds air today!
