You must be pretty brave to even attempt driving with these in snow. Mine are sitting in the garage making me miss my summer setup

 

i have the same tires, and i havent put my winter setup on, hoping we wont get a lot of snow this year. i hate driving snows for 5 months
but it is a lot like skiing when it does snow, i couldnt get in my driveway the other day

I would bump the medical coverage on my insurance if I were to attempt this. All weather tires are bad enough in the snow and you're trying to use summer tires...

 

Yea they do suck, but they aint dangerous like holding a gun to your head. If you know how to drive at a normal speed then you will be alright.
