I don't know if its legal or not but I know there was a law suit over a dealership that plunged a tire and that tire blew up killing the whole family in the car crash.
Yes
Yes but not a plug made for a passenger tire.
No, you can plug a drive or trailer tire - you just can't plug a steer tire or use recaps on the steer axle.
To plug a bike tire in case of a puncture, first remove the wheel from the bike. Locate the puncture and use a tire lever to remove the tire from the rim. Insert a tire plug into the hole, then re-inflate the tire and reattach it to the bike.
would not plug a tubeless tire or tire tube comb.bad idea!only thing holding you to the road.think about it.

In North Carolina, using a tire plug on a sidewall is generally not recommended and may be considered illegal or unsafe. Tire sidewalls are more susceptible to damage, and repairs in this area are typically not considered reliable. It's best to consult with a professional tire technician for proper repairs or replacements, as they adhere to safety regulations and guidelines. Always prioritize safety and legality when it comes to tire repairs.
I would not plug a tire one time unless you had no other choice as in an emergency. Have the tire repaired correctly with an internal patch.
When they were repairing it they probably pushed a plug through your tire accidentally and left it, then put in another plug correctly to seal your tire.
Yes, they are legal.
It is illegal for a shop to sell you the service of inserting a plug. All shops must patch the tire from the inside. A store can sell you a plug or plug tool but cannot insert the plug for you. This is because in the past too many shops were claiming to have patched a tire from the inside when they had just inserted a plug, which is cheaper and takes an experienced tech about 3min. (as compared to 15mins.)
Practically, you can plug any tire in the tread portion as long as it is balanced afterward. However many areas prohibit this now.
