After finding out they are non-repairable I just plugged it , since it had to be fixed. I guess now they expect you to simply replace a $400 tire every time you get a small leak. Nice idea, but a little tire noise is much more practical. I guess they are using noise cancelling tires on Tesla, and several other new cars. These were Pirelli 255/40-21 tires.

If you don't like them, then buy a set of tires that don't have them.
Tesla's, all the ones I have seen have Michelin (I forget which ones) or Continental ProContact TX tires from the factory.
An electric car that doesn't emit tire noise is dangerous for pedestrians, as they can't hear the car coming.
If you can't afford replacement tires, then you bought the wrong car or may have to put Lionhart tires on the car.
I've seen Teslas use a specific version of the Primacy MXM4 or the Pilot Sport 4S.
GM was starting to use foam-liner tires on the Volt/Bolt. It's cheaper than the hollow-rim approach to reduce cabin noise like that Toyota and Honda are using on the Lexus LS and Acura TLX.
