2017 Audi A4 Tires & Wheels Problems

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.

CPSC: DRIVING ON INTERSTATE AT 70 MPH, SIDEWALL BLEW OUT ON TIRE. PIRELLI CINTURATO P7, 245/40R18. THIS IS THIRD TIRE IN A SET OF 4 TO FAIL ON AN AUDI A4, 2017 MODEL *DT *TR

I LEASED MY AUDI A4 IN JUNE 2017 AND I TOOK MY CAR TO DEALER FOR THE FIRST SERVICE AT 8000 MILES AND THEY SAID I NEED TO REPLACE ALL 4 TIRES AS TIRES HAS NO MORE LIFE IN IT. LATER, I CHECKED WITH THE OTHER DEALER AND THEY SAID THE SAME THING. I HAD CONTINENTAL SPORTCONTACT 6 R02 BW 245/35R19 93Y TIRES. THERE MUST BE SOMETHING WRONG WITH THESE TIRES OR QUALITY OF THESE TIRES ARE REALLY BAD. AUDI DO NOT TAKE RESPONSIBILITY AS THEY SAY CONTACT CONTINENTAL. WHY WOULD AUDI PUT SUCH BAD TIRES IF THEY WOULD NOT EVEN LAST FOR 8000 MILES?

I HAD TWO TIRE SIDE WALL DEFECTS THAT RESULTED IN "BALLOONING" OF THE SIDE OF THE TIRE. THE TIRES ARE PIRELLI 245/40/ R-18. THE CAR HAS 12,500 MILES ONLY. I FOUND OUT THE FIRST BIG BALLOON AT HOME AND NEXT DAY NOTICED THE SECOND ONE SMALLER BUT GROWING.
