We recently had two Dunlop P 235 / 50 R 19 tires fail on our car. On 11/5/21, the front passenger-side tire tread and belt began to unravel while driving at freeway speed. This happened suddenly, with no warning lights, and we became aware of the problem when we heard a loud thumping noise from the unraveled tire striking the underside of the vehicle. We immediately exited the freeway, found a tire shop, and had the tire replaced. The following week, I inspected the other tires and found that the front drive-side tire was failing in exactly the same way. We immediately had that one replaced too. Neither tire shop that replaced the tires could identify a cause of the tire failures other than possible defects in the tires.

We purchased Nokian WrG3 225/60 R18 tires as replacements for the original tires, because we wanted all weather capability. They were installed in November of 2016. One tire subsequently was damaged due to road hazard; was replaced with same Nokian tire. In August, 2021, the tires needed balancing. The dealer (same place we bought them) could not balance them because three of the tires had belt separation. I did not check tire serial number, but assume them to be the original three we purchased new. We are awaiting Nokian's response, as the tires are warranted five years from installation. It is unusual three tires would all suffer belt separation, all made at the same time. Logic would say it is a manufacturing defect.
