Ain't done nuthin'.
The Continental ExtremeWinterContact tires are now almost 3,000 miles old, and they've gotten seriously tested since Nov. 23rd around here; black ice, white ice, deep unplowed and plowed snow, slush, freezing rain, we've had it all.
GREAT tire, with excellent lateral grip.
When they do lose traction they do so fairly progressively.
I should add my VSC/traction control is completely disabled due to the lack of mounted tire pressure sensors

I haven't crashed (yay!).
Underbody flaps still attached. One with wire ties.....
