It could be a way of preventing reliance on inaccurate pressure sensors. Don't think I've ever seen an overinflation warning though.

Yes, I think that's why and because of the varying factors that can affect the pressures - climate, tyre size and width, speed etc., so better to stick with a deflated and punctured warnings - as they have more impact and one can check the pressure hopefully with a more accurate gauge at the garage when checking pressures.

Mine work perfectly and have never let me down - even when I thought one was playing up - turned out it was a faulty valve so had it replaced.
