NHTSA Complaint #11426691 — 2017 AUDI A4

While driving on Interstate at normal speed the tire pressure light for the driver rear came on. There was no road debris or road hazard material present. On exiting the tire was going flat . The car was placed on the jack and removed and noted tread separation and protruding steel belt wiring . The steel belt wiring protruded through the tread in several places up to several inches away from site of the tread separation and exposed steel belt material . There was probably 10000 miles on this tire. The tire was purchased from the Audi dealer in Charleston , SC. The dealer was 100 % unhelpful in requesting help with having Pirelli inspect this tire for its structural failure. I have had multiple emails with Pirelli and they have been unhelpful with my request for them to examine this tire failure. I feel there is a manufacturing defect that needs to be evaluated . 245/40 R18 97H M+S I have the tire at home for inspection. The photos do not show the protruding steel belt wires well.
