I'm not sure if they are the same thing that you are talking about but dh changes the tires on my work truck (Tahoe) and on his work truck (Ranger) the day after Thanksgiving. He changes them back in early May.
My usual tires are just the regular stock tires it came with. The other tires are nobby (sp?). They get better traction. I think the guys call them "mudders".
On the farm truck, we keep the nobby ones on year round. Simply, because that truck goes through the fields. Doesn't seem to harm them. But it is mainly on dirt (mud), gravel, or occassionally creek rock. Have never tried them on asphalt.
