www.tiresavings.com has them for $56 ish each. I have 2 of them on my car and am about to get 2 more to replace the 2 Goodyears i have on my car. I never drive in the snow so i have no opinions on that. They seem pretty reasonable tires for general day to day use.
I run Falken Ziex (502 series) 245/45-17's on my Trep. The 512 series replaced the 502's and are supposed to be even better. I ran mine all year last year, even through the winter and loved them. No problems in our Utah snow, in fact they handled better than the stock 15's. They're a nice tire for the price, IMHO.
