Puncture

[Charles P]

Yes it has, but I’ve been involved in tyre pressure monitored cars for nearly 20 years. In that time I’ve experienced as many if not more false indications as genuine low pressures. The danger is the light comes on and you think  oh, another false reading, not I must stop and investigate.

I find that a calibrated thumb jabbed into the sidewall of a radial tyre gives a reasonable indication of an issue. Not a substitute for checking pressures, but a useful interim test.
