2012 HONDA CROSSTOUR Tires Problems

CAR BEGAN TO SHIMMY AS IF OUT OF BALANCE IN RIGHT REAR ON ABOUT 02-01-2016. TOOK TO TIRE KINGDOM AND THEY SAID IT WAS A ROAD "HAZARD" PROBLEM WITH DELAMINATION OF THE TREAD. THERE WERE NO INCIDENTS THAT LED TO THIS OCCURRANCE IT JUST "DEVELOPED" NO CURBS OR POT HOLES HIT. THIS IS FL ROADS ARE SMOOTH. I LIVED IN OH I KNOW WHAT A ROAD "HAZARD" IS. TIRE KINGDOM, MANAGER MICHAEL DECOSMO REFUSED TO SEND IT IN A DEFECTIVE TIRE. I REPLACED WITH SAME TYPE TIRE AT MY EXPENSE. CALLED YOKOHAMA AND THEY SAID TIRE DEALER HAD TO REPORT THIS AND WOULD NOT ADDRESS THE ISSUE. ON 03-22-2016 MY WIFE WAS DRIVING THROUGH TX CALED AND SAID THE CAR WAS "SHIMMYING" AND I KNEW IT WAS ANOTHER DELAMINATION. SHE SLOWED DOWN UNTIL GETTING TO A WAL MART AND THEY SAID YES IT WAS DELAMINATED. IT WAS THE RIGHT FRONT....
