I think for a budget tire the Gislaved NordFrost 5 is hard to beat. $105 a tire for 195/60/15 installed. They are a Swedish company. I much prefer them to the Blizzak W70 and the Firestone Winterforce I had on the same car. The Blizzak's were great for one season and sucked during the second. The Winterforce were great in deep snow and sucked in every other situation. I put about 25000km a year on my winter tires and average two years per tire. On my wife's car we run Toyo GSI 5 in a 195/65/15 and they were more pricey at $169 installed but these are hands down the best winter tires I have ever driven on period. Low noise, great traction on all surfaces, and long tread life. Well worth the expense. We are on season 3 with more than 60% tread life mind you she runs only about 12000km a winter on them.
