NHTSA Complaint #11623553 — 2024 KENWORTH T680

Tread of the tire delaminated, similar to what a recap would do. This happened at 43,476 miles +or- the first time. This incident occurred In Anton, Texas. My driver got stopped safely and the tire was still inflated. Moved the truck about a 100 yards to be in safer spot and the tire then went flat. Had tire replaced with Identical tire by Loves of Lubbock, TX. Had driver bring the bad tire in, as had never seen in 18 years in business a tire do this. I have tire in my possession. At 53, 456 miles, right at 10,000 miles the newly replaced tire, did the basic same thing. A 3" piece came out of the center of tire for the complete circumference of the tire. Driver got stopped safely. recovered the piece which was still in one piece. experiencing what we did before, I had him take pictures of the tire with it still inflated and had him check the air pressure with a gauge. Tire was at 130 lbs warm with our normal cold setting being 122-123. This incident occurred near Taft, CA so I learned of Tyack Tires and Had 2 new Michelins put on and had driver bring both tires off the front back along with the center piece. I have tire in my possession. My dealer sent tires and center piece to Goodyear for damage claims, as both times it destroyed the entire fender linings and headlight. Goodyear declined damages stating "Over Deflection", which is chronic underinflation, but that is not the case. I had request in writing for my tires to be returned along with the piece. They shipped tires back without the piece, I requested the piece again and received an email stating there was no piece. My dealer says it was sent to them that it was placed inside the tire that it came off of. I've been doing business with this dealer over 16 years, maybe closer to 18. I have pictures of the tires and piece and all damages. I had the same steer tires replaced on the twin to this truck, VIN ending in [XXX] , with new Michelins as well. I have 3 undamaged tires as well. All can be Inspected. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF IN
