I believe there is a thread somewhere on this but have not found it. I know Tesla has a kit and there are some other kits, compressor and some sort of injectable plug material. While researching repair kits, a NAPA salesman said that "Slime" required the tire to be removed before injecting it and then the tire needed to be rolled about to coat the inside and hopefully find and plug the leak/hole. Further, I got the impression that at least some of the compressors would only inflate the tire if it is off the car. Does the tire always need to be off the car for such "on the road" temporary repairs? Thank you.
