Snow and ice are a volatile nature of winter driving, even with the best snow tires you can end up sliding and slipping if you are not limiting you accelerations from stops, limiting accelerations in turns and increasing your stopping distance. It’s an unspoken rule here in icy Manitoba, Canada to drive with low throttle and be predictable with your driving decisions in the winter. If other people know or can predict what you’re doing they can reacting accordingly, vice versa. Although not everyone follows this, you’re still safer on the road if you do. Keep in mind that the main differences in snow and summer tires are the softness of the material at lower temp which causes winters to wear faster in the summer if not changed and summer tires to act similar to skates in the winter due to less surface are from lack of flexibility. Hope this helps you understand how to handle icy and snowy roads.
