Crazy Winter tires?

Hello all!

New Prius owner here (2008), and I am starting to plan out what kind of winter tire to use. I live in Buffalo, NY, where snow and ice is crazy (something we call "lake effect snow").

I want the most aggressive snow tires possible for my prius. I am already working on making a grill block for winter (in two parts, for upper and lower).

I would rather have something like studded snow tires, or even crazy mud tires if I can fit them on my little prius.

What do you recommend????

Thanks,
Paul

(and no, don't tell me to buy a truck. I have one of those as well, but I travel ALOT for work, and really don't want to make the silverado my normal, daily driver. and here in Buffalo, go get 4 feet of snow in a day is not uncommon.)
