^^^word, that would be the pug, right?
I would think the nature of the road surface, specifically it's roughness, would determine how well metal studs work on it. If there are lots of little holes and divits for the studs to settle down into, then the tire might FEEL weird, but it will hold. On smooth concrete, I'm quite sure studs WILL slide easier than rubber.
I lost the front end on the Hakkas coming into the parking garage of my old apartment last winter (on smooth dry concrete) in a corner that I know rubber tires could have held. The wipe was clearly own damn fault, but the point remains.
