I needed to repair small screw hole right in the middle of a 2019 Audi tire, only to find out the stupid tire is lined with acoustical foam rubber. Never seen anything like it before, and didn't know how to repair it, since it would be a big mess trying to rip out a section of foam for a patch/plug. 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.
