Out of curiosity, were yours machine siped, manually siped, or just
"came that way"?
I was planning on doing it manually with a hot knife, no more than 1/4"
into the tread block, and no closer than 1/2" from the edge of the block
to the first sipe. I was considering running a 1/4" groove across the
block 90 degrees from the direction of travel to give it more "bite" on
snow.
