I’m just being a little pedantic here, but miles are only a unit to measure distance not area.

Yeah my car mechanic told me that some cars/manufacturers have exactly this design flaw where the end of the broken spring slides out and pierces the tire. He mentioned that also BMWs do this. I previously had a VW Golf and had broken springs like 4 times (used to drive a lot on unpaved country and forest roads for work) which luckily doesn’t do this. The rest of the spring stays in and sometimes we only noticed a spring was broken again during inspection. Sometimes I heard the broken part rattle while driving on uneven terrain. Don’t know where I would have ended if every broken spring had pierced a tire…

s-tui But not totally sure it has every metric you mentioned.

The writing is on the wall? Like with brown letters on the toilet wall?
