Tire Problems of Land Rover Range Rover Sport

I purchased four bridgestone alenza as ultra tires (255 / 50r 19 107 w xl front and back) from costco at 2700 potomac mill circle, woodbridge, va on 12/1/2022. These tires were specifically for a 2009 Range Rover Sport hse. The odometer reading was 105632 at the time of purchase, and the tires were installed on 12/13/2022. The present mileage as of today is 118233. However, after a mere 12,000 miles, all four tires are cracked along the bead inside the tire, showing the threads/wire. The tires are all torn in the sidewall at the bead above the inside of the rim edge and are non-repairable. There was no damage to the rim, nor any reason the tire might have been lacerated by the rim. The tire failure appeared to have occurred without provocation, and costco had just conducted maintenance in April 2024. The tires have an 80,000-mile warranty, so I wonder how all four tires have the same issue on the inside of the tire after only 12,000-mileage has been recorded; it has been only two years. If the tires had failed while driving, this could have been catastrophic for me and my family, which could have ended up in the vehicle losing control and possibly loss of life since all four tires are damaged. The only driving is taking my son to school and driving in the local area for food. I had a tire inspection done with cosco tire in April 2024, and firestone identified this issue during a wheel alignment on all four tires in June 2024. I took the vehicle to ntb and had a mechanic look at it, and the only conclusion they stated was that these were defective tires. This could have been an improper service by costco, which they said was not there back in April 2024. The only warnings I had were the illuminated lamp of the tpms, the tire pressure monitoring system, and the low-pressure warning for the tire the vehicle was brought to costco for two inspections regarding the tpms, and all the tpms on the tires were working correctly; they could not determine the cause of the lamp.
