I've had loads of fun with the ubiquitous 'tyre' sniffer PID that is used widely in industry.

Photoionisation detectors are not good enough to be the device that decides that a competitor is dq'd.

I had one at home to experiment with and to run tests with.

You can send them haywire very easily with some non tyre softening substances and they fail completely to detect certain substances that soften tyres.

It's a bit like trying to keep up with cyber criminals, you can't.

Tyre manufacturers publish Shore ratings for their tyres so if a tyre isn't outside of this measurement, could it still be 'illegal' if a chemical is detected. Is that even fair to exclude it?

Tyres can come into contact with chemicals quite innocently but maybe there IS a chemical that it can come into contact with deliberately that is undetectable with gas chromatography because it can't be vaporized without decomposition.

Laboratory testing comes close to being the definitve indicator but not 100%.
