They came with donuts, not full size spare tires. If you need an actual spare you want to keep in the trunk find someone with ANY 94-04 stock 17" rim that is curbed to **** or whatever and they are just giving it away for free or a 6 pack and go pick it up. Then buy a used/plugged tire at a local gas station or wherever and have them mount it. Boom, cheap spare.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
