Hi Len,
Siping may have some benefit on ice. For normal driving it would reduce
tread support & grip. In the case where a road tire needs more dry
traction in competition, they are often shaved to a lesser tread depth
to reduce tread flexing. Siping would increase flexing. Of course the
ultimate for dry traction would be a slick.
