I'm interested in this too. I'm concerned because the description on TireRack says they rubber could crack and you will need to replace the tire. I'm running PSS and haven't had a problem but I would like to get the 4S. I can deal with reduced grip in cold weather but not having to replace $1200 worth of tires because they got too cold.
Going to get down to 10F here this week. The Z stayes in the garage overnight but will be sitting in the cold all day at work.
