WHILE DETAILING MY CAR, I NOTICED A SMALL CRACK IN THE SIDEWALL OF THE LEFT REAR TIRE. IT BEGINS WHERE THE TREAD MEETS THE SIDEWALL AND EXTENDS 1.5" TOWARD THE CENTER OF THE WHEEL. THE CRACK IS ABOUT 1/4" DEEP. I CAN SUPPLY A PHOTO IF YOU WISH, PLEASE EMAIL ME IF YOU'D LIKE ONE. THIS TIRE HAS BEEN REMOVED FROM THE VEHICLE, AND NONE OF THE OTHER TIRES HAD SIMILAR CRACKS. THE TIRES HAVE NOT BEEN ABUSED IN ANY WAY. THANK YOU! *AK( DOT NUMBER: EJH8CFE429 TIRE SIZE: 225/45R17 )

WHILE TRAVELLING AT 35-40 MPH, I HIT A SMALL BUMP AND TIRE BLEW, ALSO THESE TIRES WERE SOLD AS AN ALL WEATHER TIRE, I WAS ASSURED BY SEVERAL AUDI SALES PEOPLE THAT THEY WERE AND AT APROXIMATELY 200 MILES I HAD TO PURCHASE SNOW TIRES AS THESE TIRES ARE DANGEROUS IN EVEN A LIGHT DUSTING OF SNOW. I PURCHASED MICHELIN ALPINES FOR SNOW, BUT, HAVE NOT REPLACED THE BRIDGESTONES FOR NORMAL DRIVING AS COMPETITIVE TIRES WOULD BE AT LEAST $800 DUE TO THE SIZE AND SPEED RATING. *AK( DOT NUMBER: )
I DISCOVERED A SIDEWALL BULDGE WHILE WASHING THE CAR. I CHANGED THE ONE AFFECTED TIRE WITH THE SPARE AND I AM MONITORING THE OTHER TIRES. I DON'T KNOW IF THIS IS A SAFETY CONCERN OR NOT. HOWEVER ON A HIGH PERFORMANCE CAR I DON'T WISH TO TAKE ANY RISKS WITH MY TIRES.( DOT NUMBER: TIRE SIZE: 245/45/17 )

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2000-2001 Audi TT Coupe, TT Roadster, 2000-2002 A4, and S4 vehicles equipped with Non-Azide Driver Air Bag Inflators (NADI) that do not contain phase stabilized ammonium nitrate (PSAN) propellant. Due to a manufacturing issue, the NADI inflators may absorb moisture, possibly causing the air bag to deploy improperly in the event of a crash.
Consequence & remedy
Consequence: In the event of a crash necessitating air bag deployment, the air bag may not properly protect the occupant, increasing the risk of serious injury or death.
Remedy: Dealers will replace the driver frontal airbag inflator with an alternative inflator, free of charge. Owner notification letters were mailed November 2, 2021. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69CJ.
