My comment was based on information from Washington DOT concerning winter
tires.  Reading the TireRack page, it seems it would not be worth it,
unless you have been driving in a state that allows studs, but are moving
to one which does not.  TireRack does not comment on restudding the tires,
but they have already been "wounded" in a sense, so probably not practical.
