We put on assurance triple tread tires on and this year, the second, started having traction problems. In the slightest amount of snow or slush on the road the car skids, when we drive over painted strips on the road it skids. We think it is the tires but we have been at the tire place, had them realign the car and check suspension and continue to have the problem, claim no one else has indicated they are having similar traction problems. Any other ideas, thank-you in advance for your insight. pck
