May I interject an ignoramus question here. I too am thinking about smaller wheels (18" all around maybe) for the winter.

I understand (1) would need snow tires and (2) they don't come in 19" size. I might try to drive with the tires I have, but the first time I can't get up the hill to work. . .

What is involved in replacing the wheels? (Just buy with tires and install?) How much would they cost?

Thanks.
