ON NOVEMBER 22, 2009 I PURCHASED 4 NEW YOKOHAMA TIRES FROM NTB, MENTOR OHIO WHO INSTALLED THEM ON A 2007 HYANDAI SONATA, REPLACING THE ORIGINAL MICHELIN TIRES. THE TIRES WERE AS530, DOT #CCLM 825 1309 4 31911 SIZE 215/55R17 94V, 31911. THE TIRES WERE RATED FOR MUD AND SNOW FOR 60,000. THE TIRES APPEARED TO PERFORM FINE, UNTIL IT SNOWED. IN SNOW, THE TIRES HAD VIRTUALLY NO TRACTION AT ALL. THIS FRONT WHEEL DRIVE CAR PERFORMED VERY WILL FOR THE FIRST TWO YEARS ON ITS ORIGINAL MICHELIN TIRES. WITH THE NEW TIRES, THE CAR LITERALLY GOT STUCK REPEATEDLY IN SNOW IN FEBRUARY, 2010. FINALLY, ON FEBRUARY 27, 2010, MY 16 YEAR OLD DAUGHTER WAS DRIVING THE CAR. SHE WAS STOPPED AT A BUSY INTERSECTION, WAITING TO TURN LEFT INTO A SHOPPING MAILL ACROSS TWO LANES OF TRAFFIC COMING TOWARD HER IN THE OPPOSITE DIRECTION. ALL HAD GREEN LIGHTS IN BOTH DIRECTIONS. WHEN SHE HAD TIME TO TURN WITH A BREAK IN THE TRAFFIC, THE TIRES SPUN IN THE SNOW, DELAYING THE TURN. SHE WAS HIT BY AN ONCOMING CAR BECAUSE OF THIS DELAY. BOTH CARS WERE TOTAL LOSSES, BUT NOBODY WAS INJURED. THESE TIRES SHOULD BE RECALLED OR AT LEAST LOSE THE MUD AND SNOW DESIGNATION. I HAVE DRIVEN FRONT DRIVE CARS FOR 30 YEARS AND NEVER GOT STUCK IN SNOW. THESE TIRES ARE SERIOUSLY DEFECTIVE. PLEASE TAKE THEM OFF THE MARKET.
