Winter Setups

FlyByGTI

Hi everyone,
Before I begin this, I know I know search button blah blah blah. I have been searching and reading up on threads for this. I also know some will flame me (flame suit on) for not only DDing my Z but also driving her throughout the winter but alas. That's the life of someone who doesn't need 2 cars and a motorcycle.

Anyway now that I have gotten all of that out the way. I was wondering what you all do (personally for your winter setups). I see the vast majority of people going with Blizzak LM-60s, some 19" (I don't really agree with that) and many running 18s.

I was thinking of going with the Blizzak because of the high level of reviews that I have seen showing them being more than competent in the snow/ice.

I guess my question is 2 things:
1. Recommendation on tire size (225/40/R19 vs 225/35/R19 vs 255/40/R18). Please note I have an 09 Touring with the sport package.

2. What are you personal setups for those who drive through the snow.
