I used my spare tire last week to assist in rotating my tires. It looked pretty scary on there. I definitely don't want to fork over the dough for an extra E0 wheel & tire, but I was thinking about just getting a single full-size wheel & tire from a regular Contour. Has anyone done this? How much should I pay for a single "15 wheel & tire (I don't need an alloy wheel, either-I don't even need a hubcap)?
