2012 Cadillac CTS Tires & Wheels Problems

ON 3/23/2019 BOUGHT BRIDGESTONE TIRE PACKAGE FOR 2012 CADILLAC CTS PERFORMANCE. MY VEHICLE REQUIRES 2 SIZES OF TIRES, 265/45/18 & 235/50/18. THE TIRES ARE ALMOST BALD ARE 265/45/18 POTENZA. ON 11/29/2019 TIRE CHECK LIGHT COMES ON TO CHECK TIRE PRESSURE TO RIGHT REAR TIRE. SINCE WEATHER IS COLD, I EXPECT THE TIRE LIGHT TO COME ON AND OFF WHEN AIR HAS BEEN PUT IN. I WENT TO DISCOUNT TIRE TO PUT AIR, AND THE TECH INDICATED THE BACK 2 TIRES HAS A THREAD DEPTH OF 2 AND UNSAFE. I IMMEDIATELY WENT TO FIRESTONE COMPLETE AUTO CARE WHO I GOT THE TIRES FROM AND INSTALLATION. THEY PUT THE TIRE UP ON A SCOPE AND BOTH 2 TIRES IN BACK WERE ALMOST BALD IN THE MIDDLE. THE THREAD ON THE OUTER TIRES SEEMED FINE, BUT THE MIDDLE SECTION OF THE TIRE WAS ALMOST COMPLETELY BALD. THE TIRE TECHNICIAN TOOK MY CAR FOR TEST DRIVE TO SEE IF THERE WERE BALL JOINTS, SUSPENSION OR OTHER ISSUES THAT MAY BE CAUSING THE WEAR ON THE TIRE AND THE TECH FOUND NONE. I GO FAITHFULLY EVERY 3,000 MILES FOR OIL CHANGE AND TIRE ROTATION AT THE DEALERSHIP SO IF THERE ARE ISSUES, I WOULD HAVE KNOWN ABOUT THEM AND CORRECT THEM IMMEDIATELY. THERE WERE NO ISSUES FOUND AND THE ONLY EXPLANATION THAT FIRESTONE CAN GIVE ME IS THAT THESE TIRES ARE NOT MADE FOR YOUR CAR SINCE IT WAS A PERFORMANCE CAR.

TL* THE CONTACT OWNS A 2012 CADILLAC CTS. THE CONTACT STATED THAT THE OEM RIMS FROM THE MANUFACTURER PREVENTED THE TIRES FROM HOLDING AIR. THE CONTACT HAD TO CONSTANTLY REFILL THE AIR IN THE TIRES. THE DEALER (LOCKHART CADILLAC OF GREENWOOD, 1287 US-31, GREENWOOD, IN 46143, (317) 865-1551) HAD NOT INSPECTED AND DIAGNOSED THE VEHICLE TO DETERMINE A SOLUTION. THE VEHICLE WAS TAKEN TO TWO INDEPENDENT TIRE REPAIR FACILITIES FOR DIAGNOSTIC TESTING. THE MANUFACTURER WAS NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 50,000.
