So last week I got a nail in one of my tires when driving home from work. Since they already had close to 18K miles on them I decided to just go ahead and replace the whole set. I ended up ordering a set of 21" Hankook Ventus tires and arranged through Tesla to have the car towed from my home to the nearest Discount Tire which was the closest Tesla recommend tire shop near me. I went off to work thinking everything would be fine...I should have known better. My wife picked up the car this afternoon and told me it seemed like there were a lot more miles ticked off the range than she expected (about 13). I didn't think much of it until I got home and brought up the energy statistics for the last 30 miles the car was driven. I think this picture speaks for itself and I bet everyone can guess when I suspect the guys at Discount Tire were having A LOT of fun with my Model S ... From what I can tell they had the pedal pinned to the floor for a good two miles. I guess I'm thankful that these guys didn't seem to damage the car of get in a major accident but boy seeing something like that pisses me off. I'll be calling Tesla first thing in the morning to request that they take at least this Discount Tire location off there recommended list and then will be stopping by Discount Tire to have a not-so-friendly conversation with them. UPDATE: After reading through these posts and talking with Tesla themselves I do not believe that my car was subjected to an extremely spirited joyride by someone at Discount Tire. More than likely the spike on this energy graph was the result of the car being left on while the tires were being replaced. My full updated apology is on post #39.
