It doesn't matter how compressible it is, its temperature still rises from pressure. That is why ice is so slippery, pressure (from a tire, foot, or ice skate)

It doesn't matter how compressible it is, its temperature still rises from pressure. That is why ice is so slippery, pressure (from a tire, foot, or ice skate) melts a thin layer of water on the surface which acts as a lubricant (which is also why ice stops being slippery when its temperature gets low enough that normal pressures can't raise it enough to melt).
