2002 BMW K1200RS Tires Problems

I PUT SHENKO MOTORCYCLE TIRES ON MY 2002 BMW MOTORCYCLE. AFTER ABOUT 3000 MILES THE TREAD SEPARATED FROM THE TIRE BASE. I COMPLAINED TO SHENKO AND THE DEALER I PURCHASED THEM FROM. THIS WAS A LIFE THREATENING SITUATION ON A MOTORCYCLE WITH A PASSENGER. I HAVE DONE RESEARCH AND THIS PROBLEM IS MORE COMMON THAN IT SHOULD BE. SHENKO SHOULD NOT BE SELLING INFERIOR AND LIFE ENDANGERING PRODUCTS IN THE USA. PLEASE RESPOND AND LOOK INTO THE QUALITY OF THIS IMPORTED PRODUCT, THERE WILL BE DEATHS IN THE FUTURE WITH THIS TIRE. I CAN SUPPLY PHOTOS IF YOU LIKE. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

ROAD DEFECT ON BRIDGE ON I-70 WHERE IT CROSSES I-270 JUST WEST OF ST. LOUIS, MO. DRIVING IN THE RAIN WE HIT A METAL JOINT THAT RUNS LENGTHWISE WITH THE BRIDGE IN THE RIGHT TIRE GROOVE OF THE LEFT HAND LANE. BEING RECESSED INTO THE ROAD, BEING METAL, AND NOT VISIBLE UNTIL WITHIN ABOUT 40 FEET OF THE OBJECT, IT IS NEARLY IMPOSSIBLE TO MISS AND IN OUR CASE RETAIN CONTROL OF A MOTORCYCLE WHEN IT IS RAINING. JUST SOME APPROPRIATE SIGNAGE WOULD HAVE PREVENTED THIS ACCIDENT. THE TOWING COMPANY TOLD ME THAT THERE ARE MANY MOTORCYCLE CRASHES AT THIS LOCATION EVERY TIME IT RAINS. I CERTAINLY WOULD LIKE TO KEEP SOMEONE ELSE FROM HAVING THE SAME RESULTS AS WE DID. THANK YOU *AK
