Just switched to studded tires on my bike today (Schwalbe Marathon Winter). They make a HUGE difference. With my old tires I nearly hadn't any grip at all today. With the studded tires I can break on black ice and it feels like breaking on dry concrete. Yes - they've been somewhat expensive. With shipping I've payed about 110 Euros. But I'll prefer investing some money in good tires, compared to crashing and landing under a car.
