After being advised by the service center that the tires that Tesla uses have a special interior where it is advised that the service center should be involved as they are equipped to deal with these tires. The service center offered to check the tire, however there would be a 1 hour charge if they didn’t find an issue. However, they did humor me by offering to do a tire rotation at 12,000 miles and they would check the tire when it was off the car. After being advised that there was nothing wrong with the tire and tires can have a 1 to 2 pound variance, I was told that I may be being a bit a… retentive about the issue and there was nothing to worry about. With that being said, there was probably no reason to be adding the extra air.
After stopping at several service stations to top the tire off when they hit 35 or so pounds to the recommended pressure it seems like most every place I stopped, the air machine was out of order. After investing in a air compressor which lasted over the next 8 to 10 months I must have put in 400 or 500 pounds in the same tire, the one that was thoroughly checked. Eventually I had to get a second air compressor as the little 12 volt things are not an industrial tool. Finally with the third replacement, I picked up a bottle of the green liquid to squirt into the tire, which by this time would keep between eight and ten pounds after a seven to ten day period, which of course is not totally flat, so still no warranty assistance. So I put possibly an ounce or so ( the instructions state to use the contents of the bottle ) out of the bottle, as I did not want to disturb the special internal Tesla tire innards. Then the tire inflated up to the 42 pound recommended pressure. This allowed the tire to retain pressure, it would lose one or two pounds a week instead of ten or so a day. After following the guidelines to relieve the tire pressure, I added another minimal amount of the green stuff, put the valve back into the stem and inflated the tire to the recommended 42 pounds. There have not been any warning alarms since. I guess this is what the service department means when one is being a bit anal retentive.
