We had the low tire pressure warning a few days ago, thankfully right as we turned onto the street where we live. We pulled into the driveway to see if we could tell where the issue was and immediately noticed one tire was low. Upon further inspection, we realized the tire was worn significantly on the inside of it, and that both rear tires were completely worn on the inside of the tire and apparently not properly alignned. The left rear tire had a leak and would not hold air. Because the wear on the tires was significant and one was flat, we could not drive the car so Tesla came to pick it up the next day. Coincidentally, we were scheduled for service a few days later for issues with the charger (it was defective when it was built we just found out).
It would apprear that the tires were not properly mounted from the time the car was built. We have about 11,000 miles on the car and received it in October 2012.
No word yet from the service center as to what happens or the status of the repairs. In the meantime, we have a Roadster loaner, which is not a bad thing. What a difference between the Roadster and the S though. The Roadster is a sexy car for sure, but a bumpier ride and no power steering! We are having fun with it, but also looking forward to the return of the S!
