What is T1 Tire?The people who work for Tesla routinely know less than the people on these forums. I don't even bother to ask anyone. I got into a pleasant "argument" with a service representative about the tires on my 2019 Model S. He had no idea what the T1 tire was and argued that they did not exist (when they were already on three of my wheels). It's not their fault. They are told nothing.
