2020 Mercedes-Benz E-Class Tires

The driver front tire was found to have failed at the time of an oil change at approximately 15,000 miles. The tire was torn at the junction of the sidewall and tread in several areas. This tire is no longer available. No incident occurred. The passenger front tire was found to have the same defect when I performed a seasonal tire change but the conditions were worse at approximately 17,000 miles. No incident occurred. The tire will be taken to the dealer for inspection. Photos of this tire attached. 245/35 R20 95Y

The side wall split on the outside of the tire and the tire deflated. I pulled to the side of the road. I have no spare because the tires are run flats. I tried to drive and within about 3 miles the tire shredded. The tread separated from the tire and made the car undriveable because the tire tread was hitting the wheel well. I was stranded with no spare. The rubber began melting and I was told by the tire shop fixing my car it fused to the rim. This tire was not made properly.
