Winter tire bike size
Hi! I'm new to winter cycling and would like some advice on tire selection. My father-in-law recently gave me is (rather well-maintained) Specialized Crossroads. It's fitted with a front suspension (I'd like to get rid of that someday) and a suspended seatpost (I'd like to get rid of that too!). I first intended to sell the bike but I now consider using it as a winter bike, for quick rides in the neighbourhood to keep in shape in between nordic skiing outings.
It's currently fitted with Specialized Infinity 700X38s. I tried them in snow over ice (I live in Montreal, where we have real winters!) and was pleasantly surprised to see how fun it is to ride in the conditions. I'd like to switch to dedicated winter tires and was eyeing the Schwalbe K-Guard HS 396. I see they come in 30, 35 and 40mm width. I was planning on buying the 40mm, but I wonder if these aren't a bit too wide. Is there a more "common" size for winter biking in snow and on ice?
(I apologize if this question has been asked 153 387 times before ...)
Thanks!
