I found a awesome deal for some 245-45-17 Blizzak tires 400$ I was just wondering if there would be a huge fitment issue. I also have Tien s tech springs and these are for stock wheels

I'd prob vote against that fit to be honest. Its already taller than normal in size and snow tires are a lot more aggressive, especially in the shoulder area. With the springs and that tire being 26" in diameter I'd bet you're going to run into rubbing issues.
