from my research and the test drive's I've done on the Avenger, it handles winter driving really well, far better than what I expected.
the Avenger I tested at my local Dodge dealership had factory all season tires and drove fine in the snow. I noticed it had all seasons after driving it and looking at the wheels!
But i don't know where you live, so I can't say if it will be the same with you.
I say spend the extra, put some summers on your nice wheels, and buy some cheap steelies with winter tires.
NEVER cheap out on your safety.
