Here in the Seattle area where it usually rains but ice can come at anytime. I figure on leaving my studded tires (Schwalbe Marathon Winter) on until Springtime. Just like cars do.
My thinking for keeping them on is never knowing when ice will be present and avoiding if at all possible since falling on the ice a month ago and the bus doesn't run on Saturday.
If anything I accept riding a little slower over the 18 miles route each day. I'm running at 45 psi in the tires.
Any thoughts on this?
