Tire Sidewall problems of the 2009 Honda Accord

Driving at 45 mph and rear general tire altimax rt43 tire blew out. No accidents or injuries but consider myself lucky as this could of been serious at highway speeds and if a front tire blew out. Tire is available for inspection. Tire shop noticed dry rot in bottom of outer tread grooves and vehicle was garage parked approximately 50% of time. Tire was manufactured in November 9-15, 2020; installed on vehicle on 8-2-21 with 137,739 miles; tire replaced on 8-23-23 with 160,103 miles. Tire had 22,364 miles to failure, and was driven 2 years and 16 days to failure. No low pressure tire warning on vehicle at or before tire blew out. Tire mechanic said all 3 remaining tires had normal pressure. Tire separated into three sections, the thread area, and both sidewalls. Looks like there are safety recalls on various general altimax rt43 tires due to manufacturing defect from over curing, but this tire size was not mentioned. Tire size is 215/60r16. I have copies of installation paperwork documenting tire dot number, odometer readings, and install date as well as final replacement paperwork documenting odometer reading and dates.

Michelin, "primacy", 235 45r18 -- mxm4 soft sidewall gives smooth, soft ride, but may contribute to a "mushy", "jello-like" sway in turns tire w/ less than 3000 miles blew-out for no apparent reason at 75 mph, on an interstate, clear weather, warm & sunny, but tire had been driven in hot ( + & at interstate highway speeds ) conditions during previous week. Driver did not see or hear, nor was there any object in the road that might cause prior damage to the tire -- it just blew-out". The tire was totally destroyed by the time the driver could decrease speed and move from the far left lane ( of three lanes ) to the shoulder. Owner/driver had driven 50,000+ thousand miles on a previous set of michelin "pilot" tires ( same size, same car, same driver, same variety of conditions ) without any problems -- and plans to immediately replace the three remaining "primacy" tires.
