Need specific winter tire / rim advice. I'm completely ignorant!

[Portlis]

Hey guys, I'm basically here begging for help because I'm by far the most ignorant and uninformed person on the face of the earth when it comes to purchasing new tires.

I thought I had about a month left to deal with this, but here in Minnesota we just got our first snow fall of the year ALREADY! It usually doesn't snow until mid December these days.

So I need new winter tires for my 370. From my understanding, it's going to be a lot easier on me (and the stock summer tires) if I just get a complete new set of rims along with the tires. So that's what I'm looking to do unless I get other advice.

I've read through the past couple months worth of posts, and although there are a few suggestions such as "get blizzaks" or "blizzaks suck, get alpins" and the like, I still don't know what I specifically need. My main problem is that I see a lot of numbers thrown around, but I honestly don't know what a lot of them mean.

The biggest concern I have is buying tires that won't fit over the sports package brakes, because that seems to be the problem other people encounter.

Here's my level of understanding:

I have the sports package, so I understand I have 19" tires and very large brakes and will need to find tires that fit around them.

I understand that narrower tires are better in the winter for obvious reasons.

I also understand the basic difference between summer / all season / winter tires and why they are better for certain conditions.

Beyond this, treat me as though I was your grandma (unless your grandma knows about tires, in which case she definitely knows more than me!) and knew nothing, because that's basically where I'm at.

There's a lot of very general information out there, but no specifics. If anyone could provide specific links to websites selling tires / rims that will definitely work, I'd greatly appreciate it. Or even list out the specific rims/tires that you yourself have purchased for your sport package 370Z for winter driving.

Price is a concern, but just getting these and being done with it is a bigger concern.

Basically, what would you buy in this situation?

I greatly appreciate any response.
