The stock Bridgestones traction is as bad in snow as it is good on warm, dry roads. After driving our 180Q 30 feet in 1" of snow, I parked it until I got snow tires.

The 180Q becomes amazing in the snow with Blizzak MZ-01s, so much better than our Explorer with studded tires. The205-55-16 Blizzaks are also very quiet and smooth relative to OEM Bridgestones.
