look into what "sipes" are.
they are additional edges. those additional edges can be found in more ways than cuts in tread blocks.
and you're now assuming what i was referring to.
rather than try to explain the entire science of tires on ice, i'll now bow out of this side thread.
i've had two articles on tire pressures, tread, and tire compounds published.
