My spare tire has been flat for quite while, it won't hold air since the rim had rusted and pitted from sitting in the water-filled wheel well before I got the car. I was in the wrecking yard looking for a short drive shaft from an early 240Z and thought the local 1971 240Z might have one. The drive shaft was the typical 280Z length, so that was a no-go, but the spare tire in the car still had air pressure and looked in decent shape. So I bought it for $15.

I just looked up Bridgestone RD-150 to see what I had and how old it might be and find that it's probably the original 1971 spare tire. 40+ years old. They sold it to me as a "space saver" mini doughnut tire so I guess I'll use it the same way and stay at low speed if I ever have to put it on.

You trust a 40 year old tire as a spare? Did you find this thread on the spare tire? The wheel is useful, but do yourself a favor and get a new tire put on it for a spare.

That's why it's a "funny?" story and I'll be driving at low speeds if I ever have to put it on. It's better than a flat spare.
