Hi All: I've had the continental x-ice xi2's installed for a few months on my nearly 2 year old MS and they've performed excellent this winter. I have, however, noted a significant loss in range. Do winter tires create much more friction over all season tires? During warmer months, I averaged around 280-300 wh/mi and colder months would come in around 330-350 wh/mi with all seasons. With this setup, I'm averaging over 400 wh/mi pretty much every day. Would love some feedback on if this out of range or to be expected. Winter tires are great, but if I had to take a road trip, this would seriously cause me some range anxiety.
