So for the 2nd time in less than a year, I have a tire puncture on my Model S that can't be repaired. Each time, Tesla charges roughly $450 for a new tire, mounting, and balancing. A 245/45R19 Michelin Primacy MXM4 tire runs about $200 from a place like TireRack, so figure with shipping you could maybe have a 3rd party install a new tire for no more than $300 (probably less). With this happening twice in the last year, that's over $300 overpaid for tire service over the last year. That's enough that it would have paid for a pair of the JackPoint Jack Stands. Why JackPoint Jack Stands? Because I don't trust anyone other than Tesla to lift the car, and you can't jack up a Model S effectively and put it on stands (long enough to get wheels off in order to take them into a 3rd party service center to replace, mount, and balance new tires) without a way to put stands on the same point as you jacked from. Moral of the story is, if you are a do-it-yourselfer and don't have them already, buy the JackPoint Jack Stands now! They pay for themselves in only 2 tire replacements, and as I am now a cautionary tale for, it can happen in less than a year. And again to all those who say they never or rarely ever have tire punctures where you have to get repairs or use a spare, here I stand. Twice in less than a year, sidewall both times.
