I started using studded snow tires on my MTB 10 years ago on my old commute routes. One winter was very icy and one of my favorite things about it was pedaling up this one icy street where cars would always be stranded. My least favorite thing was this one long residential street where the ice kept melting and refreezing into deep tire ruts, lumps and bumps. I never fell, but the bike would be thrown around and I had to keep sticking a foot out as the slow forward progress would be stopped by a rut or ridge.

There was also a large flat parking lot by a lake where, pre-studs, an unexpected ice sheet appeared mid left turn at speed and my wheels slid out to the right. I slid across the ice until reaching dry pavement where the wheels hooked up, I was thrust upright and continued on, amazed. Years later I encountered the same ice sheet conditions at the same location and the studs did their thing, keeping me upright and secure. Of course, after the first icy slide I was always remembered there might be ice there...even in the summer I'd remember.
