Default Does a tyre change its CIRCUMFERENCE when underinflated?

Answer. not by very much, if at all.

This seems to be a perpetual urban myth.

It tyre pressure sensors are using this, it has to be a very very
complicated bit of software to detect - say - less than 1% change in RPM
relative to the other wheels.
