Don't yell at me. I'm a lazy bum. I have had a slow leak in my drive side rear tire for over a year. I need to put in 3-5 pounds every 10 days or so. I searched oh so many times for a nail or screw and nothing. Someone said it may be a bad valve? I got the car in May 2019, so it's possible it was there since the beginning. Anyway, I called Mavis and asked them if they have had Tesla's in before because they cannot go up on the left (or so I heard). They said yes. Made an appointment for a few days later. Got there and first thing they asked for was the key. Bad sign. Then I asked them if they knew it cannot go on the left and desk person had to go into back and ask. Came back and said Tesla's use run flats and that they cannot fix them. This is the first I heard of this. Maybe a model S has run flats, but does the Model 3 have them? And how would they even know what tire I have without looking? So I left. What reputable place that knows what they are doing do I need to take my car to? And if anyone local knows of somewhere they went, please help. I am on Long Island.
