To all those posting misinformation about being safely being able to use summer tires in winters where the temperature drops 44 degrees Fahrenheit, please read the article that I posted in this thread

Shawn said "The transition temperature where summer performance tires or all-season tires lose traction and winter tires enter their peak operating window is around 7′ Celsius (44.6 degrees Fahrenheit)." I agree with that based on my experience of trying to use summer tires when there was an inch of snow in my driveway -- I slid a yard when I braked normally. It's the tire compound that is the most important factor.

Note that I'm not talking about All Season tires.
