THE 18 INCH TIRES ON THE 2012 HYUNDAI SONATA HAVE ZERO TRACTION ON ANY SURFACE THAT IS NOT DRY. A DUSTING OF SNOW MAKES IT IMPOSSIBLE TO DRIVE THIS CAR. TRAVELING AT 5 MPH WHILE TURNING FROM A DEAD STOP INTO THE NEIGHBORHOOD ON A LIGHT COATING OF SNOW CAUSED THE CAR TO SLIDE OUT OF CONTROL AND HIT A LARGE ROCK CAUSING FRONT FENDER/ BUMPER DAMAGE THEN BOUNCED BACK ONTO THE ROAD. THIS IS NOT THE FIRST TIME THE CAR HAS SLID ON ANYTHING BUT A DRY SURFACE. ALL LAST WINTER, WE HAD TO LEAVE THE CAR IN THE GARAGE IF THERE WAS ANY SNOW ON THE GROUND. WE HAVE NEVER HAD THIS PROBLEM WITH ANOTHER VEHICLE. IT IS UNDRIVEABLE IN ANY SNOW. I HAVE COMPLAINED TO THE DEALER AND THEY SAY THEY HAVE HEARD ABOUT COMPLAINTS ON THE 18 INCH TIRES, BUT OFFER NO SOLUTIONS. THESE TIRES ARE A HAZARD AND NEED TO BE REPLACED. I HAVE LOOKED FOR SNOW TIRES OR OTHER SOLUTIONS, BUT THEY ARE NOT MADE FOR 18 INCH WHEELS. *TR
