I am curious how siping reduces contact area by any significant amount All the sipes I have seen are just slices through the tread block.

How does a smaller contact area reduce traction? Reduced area means more weight on the now smaller area, end result is amount friction is the same.

More squirm I get but is that a problem for a non performance driver?
