Winter tires have a softer compound and tread pattern. That means the tire needs to slip more to generate grip than a summer tire. It will give a slightly floating sensation for the driver, but the grip is still there. The DSC system sometimes cuts in too early, thinking the car is starting to slide out of control, even if it isn't. With nordic winter tires (very soft) this can be a big problem. The solution is to run in DTC mode (allows more slip), or run a tire like Michelin X-Ice 3. This tire has small locking edges in the sipes that stop the tread pattern from bending too much.
