These tires should be taken off the market. Purchased new Jeep Cherokee Summit Reserve summer 2024. Followed the recommended oil change/tire rotation. The 17,000 mile oil change appointment found uneven wear on tires. Called Continental tire regarding issue- they said it was from over inflating tire and it was a Performance tire. I never added air lb pressure but no mileage warranty because bought new vehicle. Nobody wants to admit (Jeep/Continental) these are junk. Ive never had a tire howl or end it’s life this fast. I’ll never buy a new vehicle again without asking about tires and mileage warranty. Continental doesn’t stand behind its tires…

Great tire.
