Bike till snow starts and then use public transport and walking, do deep breathing exercises outside every day and go for long walks on weekends to temper yourself for winter proper.
If you insist, go for studded Marathons because you won't be offroading in snow anyway, and mittens go on hands, not on handlebars.
