I just use all season radials. Don't drive the cutlass in the winter, but my dad uses Futura GLS's (rwl pepboys tire) on his fairmont (fox body, probably the closest to a cutlass that gets driven in winter) in the winter. It gets enough traction to drive through anything he needs to; up to and including 1' of snow. You can't drive like you're in a rally race, but they work fairly well on that car. Also, they allow you to lose traction when wanted... An added bonus. 🙂
