NHTSA Complaint #11578678 — 2002 FORD F-350

[XXX] tire on driver's rear began to have significant vibration while towing 16,000 lb. fifth-wheel RV. Stopped and visually/tactilely determined unusual wear pattern so went to commercial tire shop in Pahrump, NV. Their inspection determined tread separation rendering the tire unusable so we replaced it with a different brand. This is the second of three tires installed at the same time that have suffered tread separation failure. The first was in July 2023 and was not reported to NHTSA, but when two more tires failed at the same time, I decided to report. Because this type of failure does not produce TPMS warnings, it could have been a catastrophic failure that might have resulted in damage to our vehicles and/or a crash with significant injury to us or other motorists. With three failures from the same batch of tires on our vehicle, I believe there is a serious problem with this batch of tires and they should be recalled.
