Well, a the Valk motorcycle tire is basically similar to a grooved slick. With all the comments about improved traction and braking of a dark side tire I got to thinking of how to improve the wet weather handling and braking of the "grooved slick" Valk tire. One way would be to sipe the tire. I was just hoping that someone had or heard of direct experience. I ran across the same information doing a Google search along with the picture you posted. However I don't recall any information on siping cruiser tires specifically. For what it's worth I ride almost year around but there can be frost on the roads this time of year and this is also our rainy season.
Hey Farther.......try it, see what it does, its been done on bikes but not very often I suspect, and info on effectiveness wont be plentiful or reliable, so try it and let us know, that way youd be the expert
