Tire Related Problems of the 2019 Subaru Legacy

Tire problem

After my 2019 Subaru Legacy 2. 5i limited sat outside on a level blacktop parking lot for one week (05-03-23 to 05-10-23) without moving, both passenger side tires were discovered completely deflated. The tires were goodyear eagle LS-2 size 225/50r18 95h (front passenger dot m678 jr2r 1819 and rear passenger dot m678 jr2r 1719). The tires were original to the car when purchased new by myself at jenkins Subaru in bridgeport wv on 09-23-19 with 26 miles on the odometer. The tires had 32,515 miles on them and were rotated 6 times. Sever dry rot on the tires sidewalls was the reason given by the goodyear technician, goodyear service center, 149 green bag rd, morgantown, wv, 304296-1748, for complete deflation. It was also recommended that the remaining divers side tires be replaced as they were also displaying sidewall dry rot (front drivers dot m678 jr2r 1719 and rear drivers dot m678 jr2r 1819). All four tires were replaced with new goodyear eagle ls2 tires (2 on 05-10-23 and 2 on 05-12-23).
