2021 Dodge Durango Tires Problems

I had 4 Pirelli tires that were down to 3/32 to the point where the threads were showing near the inner sidewall on the tread in under 15000 miles. Tire information: Pirelli Scorpion Zero All/Season run flat tires Tire Size: 295/45/ ZR20 (110Y) M+S My safety as well as others would've been at severe risk if I wouldn't have replaced my tires. They would've blown out near the inner sidewall on the tread. I brought my vehicle in to the dealership to have an alignment and all specs were in spec which would indicate there shouldn't have been premature or uneven wear on the tire. They did confirm that under 15000 miles is extremely premature for these tires to be worn. The tires have only been inspected by the dealership, nobody else at this time. There were no lights on the dash indicating any sort of issue. I called Pirelli about the issue and they stated that there is no mileage warranty on the tires put on at the time of manufacturing. They stated that this complaint was "definitely not the first they have heard and it is not uncommon for premature wear to occur" but couldn't provide any further comment.

All four tires have worn down after only 18,600 miles. They are bald after only minor use.
