Perhaps it has to do with the longitudinal spacing of tires.

I saw that, or similar show, some time ago and do not recall if the spacing of tires is any different from say an 18-wheeler. But, if you imagine yourself as a spot on the ice that will pressed on by say the rightmost tires. You'll experience a "bump.........bump.bump..............................bump.bump". I suspect that the paired bumps, if close in time might act like a jack-hammer. But, it's just a SWAG.
