I don't have a lot of experience with what's repairable vs. in need of replacement in these circumstances and could use a hand. attached is a photo of the nail in the tire. when I found it I called Tesla's 800 number and they told me their policy was strictly replacements, no repairs. I've had a tire in a Subaru repaired, and as the guy who helped me out said at the time, the repair was nothing to worry about at all. now, I don't know if Tesla's policy is simply very conservative, or if it reflects the difference between the run of the mill tires on the Subaru and the tires on my Roadster (Yokohama 175/55 R16 80W). is this being a high performance tire an issue? I don't want to do anything foolish to save some money, but I also don't want to walk into the repair shop totally ignorant and susceptible to them playing games to sell the guy with the expensive car new tires.
