    My 74 Z28 has a 14 inch space saver tire that seems original based on the date codes but I'm curious if the 74 z28 which came with 15" tires would have come with a 14" spare? F78-14
    If it's original, I may keep as an ornament in the trunk but itf not I'll probably sell.
    I wouldn't expect it to inflate and sure wouldn't rely on it if I had a flat.

    I don't think 73/74 Z28s came with a space saver tire.

    It could be original. I don't know what size space saver tire was used. I have seen other GM cars with different size space saver spares from the tires on the road. The 80s Caprices I've owned had 15" tires on the road and a 16" space saver spare, so anything is possible.

    Usually if the car has positraction rear it will have full size spare that matches the other four. Might be the inflatable spare meets this need? Could be that it blows up to full size? See some of them blown up and really look bad after all these years.

    My 73 RS came with a space saver and my 73 Z28 had a full size spare, The jack locations are different.
