I've ridden as a commuter for several winters. Sometimes the studded tires
are a blessing, other times not needed at all. Though I have two wheelsets
for my Commuter, I leave the studded tires on all season. I use Shwalbe
Winter Marathons, 1.75 X 26 inflated to 70 psi. I'm monitoring closely for
stud wear...about 500 miles on them so far, +70% bare pavement and the
tires still look like new. All maintainance occurs outdoors for me so the
less, the betterwhen it's cold out. Also, working 12.5 hour shifts in the
Great Lakes area, I can ride in to work in pleasant weather and ride home
in a blizzard. Forecasting weather around here is difficult at best, lotsa
suprise weather changes.

I believe any individual should ride whatever tire they like. Heck, back in the early
60's I used to take the old Coaster Brake bike to school every day year 'round on bald
tires, and I always managed to get through. So in my opinion, and it's only
my opinion, ride what you like...it all works and it's always fun.

Happy Trails
