sent a complaint to Michelin. They told me that the much-touted one-year warranty against operational damage is only valid if I record my tire purchase on the Michelin website when I turned it in for inspection. I'd want to give a heartfelt "thank you" to the staff at the Vianor store, where I made the nearly 90-thousand-dollar purchase, because they failed to inform me that I needed to register my tires on the website. Imagine that before you can purchase something, you have to register it with the maker. Yes, it appears that there is a guarantee even without registration, but only for a manufacturing flaw, which, of course, they didn't recognize my damage as after 3000 runs and declined the guarantee for (I'm attached screenshots to prove this). I'm crossing my fingers that they did a last seal in the show that the tire mileage is 50,000. How you can travel 50,000 miles in two months is beyond me. Or perhaps they were alluding to the tire's high mileage when they said it. In order to avoid having to buy four new tires, I was forced to purchase one from the same manufacturer. If I had known Michelin was so iffy, I would have bought the same Pirellis I skated on for 6 years and 60,000 km till they were nearly erased to zero (perhaps the tire had driven over little gravel, which the tire could not resist for 30,000per cylinder).
