well, last few years the winters have been pretty mild. But 0-10 degrees is pretty common. And it NORMALLY stays around 30 ish in the winter. And I work nights, when it's coldest. So I drive in the evenings, night, and early morning. The coldest times of the day. I just don't want to chance it on summer rubber. I could always dial it back when it was cold I guess, but why bother? It won't likely be uncommon for me to drive is sub 10 degrees, if winter ever really comes back here.
