OK, so it is the middle of summer and many of you in more harsher climates might be already prepped for anything that mother nature tosses your way (assuming you drive your RS6 in the winter and in the snow/ice/etc).

My virgin So Cal RS6 has never seen snow or ice, but she will this year as she is in PNW now...

I am looking at the Bridgestone Blizzak LM-60 on the OEM 18" rim.
There is also the WS70 but they don't have the XL rating nor are they a "performance" winter tire.

My questions are:
1. what other winter rubber is out there?

2. what size? (225/45R-18 95H XL)

Thanks in advance!
