ok, its snowing hard for one of the first times of the year here. i need to travel about 75 miles one way and then back today. by the time i come back the roads will be icy and have an inch or two of snow. i will be driving the freeway at 60+ MPH. and i have the cooper sport with the performace run flats. never driven with this car or tires in the snow. are the tires that dangerous? or will i manage????? anyone have experience with these tires in bad wintery weather??? i'm used to driving in the snow, just not with a cooper on stock sport tires. i wanted to wait before spending$$$ on winters to see if i can drive on the performace tires. my dealer said they are fine for winter. am i going to regret this????
