spare tire

That has bugged me for a while now. My dart has a 70 series spare tire, and the cardboard I bought has never sat right because the tire was too wide.

Now that I'm switching over to big bolt pattern wheels, I'm going to need a new spare. I think I'll run down to pick and pull and get a spare tire out of a Grand Cherokee. They are 5x4.5 bolt pattern and should be plenty skinny. Only thing is I don't know if the diameter will fit in the spare well.
