2000 CHRYSLER SEBRING CONVERTIBLE Tires Problems

TOOK MY CAR IN 10/23/15 TO HAVE THE TIRES ROTATED AND WAS TOLD BY THE SHOP I NEEDED NEW TIRES THAT THEY WERE ALMOST BALD AND THE THREAD INDICATORS WERE SHOWING ON ALL 4. MY TIRES HAD ONLY 20K MILES ON THEM AND THE WARRANTY WAS FOR 60K MILES. SHOP SAID THEY WOULD CONTACT FALKEN TIRES AND CALL ME BACK. FALKEN JERKED THE SHOP AROUND FOR OVER A WEEK PASSING HIM FROM DEPT. TO DEPT. RED FLAG!!!! IN THE MEANTIME I CHECKED W/ SEVERAL OTHER SHOPS AND IN ONLINE FORUMS AND REVIEWS. ALL SAID THEY HAD THEY'RE TIRES WEAR OUT IN 6-8 MONTHS OR MORE. THE SHOPS SAID BECAUSE OF THE WEAR PROBLEMS THEY WOULDN'T SELL THEM AND FALKEN HAD SHORTENED THE WARRANTY TO 40K AND 5 YEARS. MANY SUBMITTED CLAIMS AND WERE DENIED 2 OR 3 TIMES. THE SHOP WAS TOLD BY FALKEN FOR ME TO BUY NEW TIRES...

I WAS DRIVING 65 MPH ON ROUTE 495 AFTER LEAVING ROUTE 66 FROM VIENNA, VA. I WAS GETTING AN UNEVEN LIGHT THUMP FEELING LIKE I WAS DRIVING LINED PAVEMENT, BUT IT IS NOT ON 495. I HAD A VERY STRONG PULL OF THE STEERING WHEEL, AND I CHECKED MY MIRRORS TO SEE IF I MAY HAVE RUN OVER SOMETHING. I SAW THE FULL CIRCULAR PART OF MY RIGHT FRONT TIRE ROLLING ACROSS THE HIGHWAY BEHIND ME. I HAD TO GRAB THE STEERING WHEEL TIGHTLY TO BRING THE VEHICLE ACROSS THREE LANES OF HIGHWAY TO THE BREAKDOWN LANE. I WAS HELPED WITH PUTTING ON MY SPARE TIRE, BUT ONLY HAD ABOUT AN INCH OF RUBBER LEFT ON THE RIM OF MY WHEEL. I DROVE TO THE WALDORF OFFICE OF TIRES PLUS ON THE SPARE AND HAD THE TIRE REPLACED THE NEXT MORNING AFTER THEY FOUND A REPLACEMENT AT APPROXIMATELY HALF PRICE...
