NHTSA Complaint #11434707 — 2014 FORD F-250

MICHELIN LTX A/T 2 Size P275 65 R20 I have a 2014 Ford F250 SRW that I bought new in July 2014. The truck has 30,000 miles on it and 20,000 of it was towing a 5th wheel. The truck sits inside next to the 5th wheel when its not being used. I had the original tires on which had about 50% of the tread left. The rear tires are always inflated to 80 PSI before towing. We had 2 blowouts on the rear tires. The first I started feeling a vibration and thought I had a tire going down. No TPMS warnings. I pulled off and when I got below 45 the vibration stopped. The tires were all up and the tire temps were within 10 degrees of each other. So we continued on when I got back on I-75 south above 50, I started feeling the vibration again. I got over to the middle lane thinking maybe it was a pavement issue. Thats when the passenger rear tire blew. That tire was split in the side wall on both sides like the seam let go. Didn't think much of it when within about 50 miles, just south of Lexington the driver side rear tire blew. I got a little vibration that I was thinking that feels just like before the other side blew, but not nearly as much warning (about enough time to let off the gas) Same side wall split, except this also took out part of the tread and damaged the truck. Tire Discounters that was able to get us the same Michelin tires that came on the truck. The manager and his senior tire tech thought the tires were defective and told me to take the old tire and report the DOT number.
