Thought I'd share a photo of what the roads are like where I live. I drive about 5 miles of dirt road to each way. When the temperatures rise above freezing and melt the snow, then freeze at night, we get icy roads.
Last year I drove this with non winter tires. This year I got studded snow tires and it's a huge difference.
Haven't needed chains yet, but have some in the back just in case, along with a snow shovel, tracks, and a bucket of sand.
On the steep road near the house, I put down a single line of sand to give some traction on the way down the hill. It's a 7% grade and probably 100' in elevation. Makes the drive down more predictable.
If you look close enough, you'll see chain marks in the ice.
