Unfortunately, Tesla Service Centers (at least the one in Denver) don't honor Michelin tire warranty claims (so Tesla and Michelin have informed me) so I wasn't able to get my now-down-to-3mm Primacy tires replaced at a recent service visit. I mean, I could've, but I would have had to pay full price for the new tires, whereas Michelin has told me I'm eligible for something like a 40% credit on 4 new Primacy tires since they've worn down in 25K miles instead of the rated 40K+. So, that means, Discount TIre locally. I stopped by there to check 'em out. Nothing confidence-inducing came of the visit. Guy came out to take a look, he measured tread-wear, but looked at the car like it was something he'd never seen before and was afraid to touch. And now the question(s): I hear there are very explicit rules that a tire shop needs to follow when changing tires on a Model S. Like, 175 newtons or something on the torque wrench? Use only hand tools? Anyone been through this already? What exactly is the checklist of do's and don'ts I should present to Discount Tire, before I entrust them with my S? I fear my car may be the first Tesla they've ever worked on.
