Anecdotal only. My boss at my old job had a neighbor
who tired to inflate a space-saver spare tire to 32 psig
or so instead of the rated maximum.

Moden day space saver tires are usually inflated in excess of 50lbs. I
suspect his spave saver tire was old and rottten.

Old yes. Not rotten. The original ones were only to be inflated
to 12 psig or something like that. Accidents of the sort described
are why those are no longer available.

Memory dims but I think they were collapsible with the tire folded
into the rim.

Yes those were the original space savers with a canister of air for filling.
