Well they do, or at least used to when I could use a bike.

Can't say it's something I've ever experienced over 50 years and many
bikes (currently 10 solos between us, a cycle trailer and tandem).

Maybe I've never had a bike (or tyre) that might be likely to suffer

Presumably you could have a tyre come off the rim when is use then
(after being on there with no issues for some time)?
