2005 Volvo XC70 Tires & Wheels Problems

TIRE INFO PRIMEWELL VALERA TOURING 215/65/R16 98H MADE IN CHINA. DOT #5WA6 00A 4813 IN MARCH 2016 I GOT A NEW/USED CERTIFIED CAR FROM A DEALER IN ORLANDO FL THE CAR CAME WITH NEW TIRES. NOT SURE WHERE THE TIRES WERE SOLD/INSTALLED, BUT AFTER I DROVE ABOUT 11 000 MILES, ONE OF THE REAR TIRE STARTS TO LOSE PRESSURE ABOUT 1 PSI/DAY. ON 8/14/2016 I TOOK THE CAR TO LOCAL TIRE PLUS STORE IN GAINESVILLE FL FOR INSPECTION ADDRESS: 2605 SW 34TH ST, GAINESVILLE, FL 32608, PHONE: (352) 231-8422-THE TECHNICIAN CHECKED THE TIRE AND SAID IT IS FINE AND SOME AIR LOSS IS NORMAL-EVEN I TOLD HIM THAT ONLY ONE TIRE DOES THAT AND I HAVE TO PUMP AIR EVERY WEEK TO PREVENT RUNNING FLAT. ONE MONTH LATER 10/16/2017 ON THE HIGHWAY GOING 70MPH I SUDDENLY I FELT AN EXPLOSION/STRONG VIBRATION AND LOST CONTROL. THE ROAD WAS CLEAR I DID NOT HIT ANY DEBRIS THAT CAN AFFECT THE TIRES. I WAS LUCKY THERE WAS NO OTHER CARS AROUND ME, SO I COULD PULL ON THE SHOULDER SAFELY. THE POLICE OFFICER(COLLINS)CAR THAT STOPPED TO SEE IF I AM OK ,SAW THE TIRE AND TOLD ME IT WAS DEFECTIVE AND I WAS LUCKY TO BE ALIVE SINCE THE DEFECTIVE TIRE WAS ON THE BACK NOT ON THE FRONT AND TRAFFIC WAS LIGHT. I DISCOVERED THE SAME REAR TIRE I HAD PROBLEMS WITH BEFORE EXPLODED, LOST PART OF THE TREAD DUE TO THE BREAK OF INTERNAL STEEL BELT . I CHANGED THE TIRE WITH THE RESERVE AND I TOOK THE CAR AGAIN TO TIRE PLUS STORE FOR REPLACEMENT. THE TECHNICIAN RECOGNIZED THE TIRE IS DEFECTIVE BUT REFUSED TO REPLACED BECAUSE IT WAS NOT ON THE LAST RECALL FROM PRIMAEWELL .(17T-013) SO I HAD TO PAY OVER $190 FOR A NEW PAIR TIRE SINCE THE CAR IS AWD AND CANNOT HAVE DIFFERENT TIRE AND STORE DO NOT SELL ANYMORE THIS BRAND(WANDER WHY?) PROBABLY MORE OF THIS PRIMEWELL VALERA TOURING TIRES ARE DEFECTIVE NOT ONLY THOSE LISTED ON THE RECALL, CHINESE MANUFACTURING IS FAMOUS FOR KILLING CONSUMERS WITH AMERICAN BUSINESS COMPLICITY-THIS IS ANOTHER SUCH CASE.. I AM CONCERNED THAT OTHER 2 SIMILAR TIRES STILL ON MY CAR TODAY AND I FEAR THEY WILL EXPLODE
