Its a spare, designed to get you to a shop. If you expect more from a spare, you have unreasonable expectations. If you want a 5th tire, go buy a 1965 Galaxy 500, toss some bias-ply tires on it, and start rotating them every 1000 miles so you can feel good about it.
Good grief. Enough about "matching spares" already.
