If I were you, I'd skip the studs on the front wheels and go with a studless winter tire-I had studs on the front of a car once(Civic) and they would slide on dry pavement on turns and didn't last. I have a set of Semperits for my wife's Vibe and they did excellent last year(I don't drive my 300D in the snow/salt)
