2001 Volkswagen Passat Tires Problems

I WAS JUST ENTERING I-90 AT HARLEM AVE WHEN WITHOUT WARNING MY 2 MONTH OLD TIRE WENT FLAT. THERE WAS NO WARNING, AND BY THE TIME I WAS ABLE TO GET OFF THE EXPRESSWAY THE TIRE WAS SHREDDED. I CHANGED THE TIRE WITH MY SPARE AND SINCE THE TIRE WAS A REPLACEMENT ON A SET FROM NTB I DECIDED THAT I WOULD COMPLETELY REPLACE THE WHOLE SET AS I WAS COMPLETELY WITHOUT ANY CONFIDENCE WITH NTB. THE TIRE DID NOT LOOK LIKE IT HAD ANY PROBLEMS EXCEPT FOR THE DAMAGE DONE BY RUNNING FLAT. I REPLACED THE TIRES 8/9/08 AND UPON RETURNING HOME FROM THE TIRE STORE READ A CONSUMER'S REPORT ALERT THAT SOME CHINESE MADE VALVE STEMS ARE FAILING. WHILE AT THIS POINT I DO NOT HAVE THE STEM IN QUESTION THE TIRE WAS OF CHINESE MANUFACTURE AND ALL SYMPTOMS I ENCOUNTERED ARE CONSISTENT WITH STEM FAILURE. *TR

TIRES EXPERIENCED SIDEWALL SEPARATION AFTER LESS THAN HALF OF THEIR USEFUL LIFE. ALL FOUR TIRES WERE REPLACED AT THE SAME TIME. TWO OF THE FOUR TIRES HAD THIS SEPARATION. *AK

2001 PASSAT ALL NEW PIRELLI TIRES 12/03. REAR TIRES CUPPING ON THE INSIDE AFTER 20,000 MILES. VEH WAS LOUD IN THE REAR, LESS TRACTION, HANDLING FUNNY. FIGHTING WITH TIRE PLACE RIGHT NOW.*AK

THE VEHICLE EXPERIENCED A HEAVY VIBRATION, WHICH WAS DUE TO A PROBLEM WITH THE TIRES.*JB

WHILE TRAVELING FROM COLUMBUS, NE TO SIOUX FALLS, SD ON SD HWY. 50 WEST OF VERMILLION, SD, MY RIGHT FRONT TIRE EXPLODED WITH NO WARNING. THE EXPLOSION DESTROYED THE TIRE AND TORE LOOSE THE LOWER RIGHT SIDE BODY MOLDING. THE SERVICEMAN AT THE SIOUX FALLS SEARS TOLD ME HE HAD ADJUSTED SEVERAL OTHER IDENTICAL MICHELIN TIRES FOR THE VERY SAME PROBLEM. I AM CONCERNED ABOUT THE OTHER TIRES ON MY CAR AND THAT WE MAY HAVE A DEFECTIVE BATCH OF TIRES HERE. VW WAS CONTACTED BUT HAS REFUSED TO REPAIR THE DAMAGED MOLDING UNDER WARRANTY.*AK (DOT NUMBER: CXYX 1201 TIRESIZE: 195/65R15)
