LT285/60R20 with 12,700 miles. I had just left the parking lot at the Cumberland YMCA and was merging into traffic on [XXX] westbound in Cumberland Md., accelerating to the speed limit (55MPH) when I began hearing a noise. I then saw a red warning light on the dashboard indicating 0 tire pressure on the left rear tire. Looking in the outside rear view mirror I could see the tire was flat and the truck was basically riding on the rim (thus the noise). To my knowledge I did not hit any debris or potholes. I had children in the back seat. Fortunately at the low speed no one was in danger. I need to replace the tire (actually I will replace all 4 as I have no trust in Firestone) so I don't know about the availability for inspection but I will take photos. The local police were called to help ensure personal safety while the spare tire was mounted. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
