After 50 years behind the wheel I just got educated about OEM tires. THEY ARE NOT MEANT TO LAST. After getting over the trauma of buying the car and enjoying it for three years ,the warranty is up and oddly the tires are worn out too. Your OEM tires are built to manufacturers specs. And the tiremakers build them to a lesser standard FOR the car makers. MY OEM continentals treadwear number was 500. I did everything to make those tires last. The continental rep said the 36,000 miles I got was amazing life from an OEM tire . I don't think so.
