WHILE DRIVING HOME THROUGH PITTSBURGH, PA IN ABOUT AN INCH OF SNOW I CAME TO A 90 DEGREE TURN ON A RESIDENTIAL CITY STREET. I TOOK THE TURN AT NO MORE THAN 15 MPH AND THE CAR DID NOT RESPOND TO THE TURN, INSTEAD SLIDING INTO THE CURB CAUSING DAMAGE TO THE RIGHT FRONT STEERING ASSEMBLY. THIS IS NOT AN ISOLATED INCIDENT OF THE TIRES HAVE LITTLE TO NO GRIP IN THE SNOW. PAST INCIDENTS HAVE ALL INCLUDED THE VEHICLE IN MOTION, ON A HALF INCH OR MORE OF SNOW, AND LOSING GRIP WHEN ATTEMPTING TO BRAKE OR STEER. MOST INCIDENTS HAVE OCCURRED AT SLOWER SPEEDS OF LESS THAN 25MPH. MAZDA SHOULD NOT USE THESE TIRES AS THEY POSE A SIGNIFICANT SAFETY HAZARD IN THE SNOW. THIS IS MORE SERIOUS THAN ANY OTHER VEHICLE I HAVE DRIVEN WITH ALL-SEASON TIRES AS THESE PROVIDE NO GRIP WHATSOEVER IN THE SNOW.
