Tire Blowout problems of the 2004 Jeep Wrangler

On March 8, 2020 while driving at 75 mph on interstate 75, the right rear (rr) tire on my 2004 Jeep Wrangler blew out. The tires were purchased at sam's club in may 2018. The vehicle had a matching set of tires all purchased at the same time (may 18) - bf goodrich all terrain ta ko2. Size 31 x 10. 5 r15. The mileage on the tire at time of blow out was only 16,386 miles. It is very clear from photographs that rear tire tread separated from the sidewall. Weather conditions at time of tire failure were excellent - clear, sunny, 57 deg f. Roads were clear and dry. Tire pressure for remaining 3 tires was checked immediately after blow out of rr, and all 3 tires were found to be same pressure (35 psi). The tire was marked dot bf60_at11_1118. I am an automotive engineer with +30 years of experience in automotive driveline. The way the tread separated cleanly for full 360 deg from sidewall on front of tire clearly leaves me believing there is a manufacturing or design defect in these tires. I am concerned about the safety of this bf goodrich all terrain ta ko2 tire on the road.
