Tony:
I could not find steel wheels for this car. I ended up buying 4 stock 18" Crossfire wheels on ebay. Actually, I bought two complete sets, and then sold two of the 19" wheels to another user on this forum.
You will also not be able to find 19" snow tires. I bought 4 Dunlop 18" snow tires and had them mounted to the new rims. This also involves buying the TPM (tire pressure monitor) inflators from D/C and having them linked to the computer in your mirror assembly. It is not a big deal, but has to be done.
Others on this forum have figured out how to put a link to a direct post. I will have to ask them how they do it. For now, here are some of the posts that you can read about snow tires. I just did a search for "snow" in the search function at the top of the screen.

SUCKS IN THE SNOW
WINTER TIRES
Conditions here in NE Ohio for this winter - we had a good bit of the time with 1-3" of snow on the ground. Quite a few days with 4-6". A couple of 8". And one day with 10". Except for the 10" day of snow, and one day of an ice storm, my car was on the road every day. You just have to drive with some common sense.
Hope this helps.
