Then people will drive around with them at 60psi (i.e. doable but not great for a car tire) and wonder why they keep breaking belts.

Because that could not also be a citable offense?

We could also make cooking up hair brained schemes to regulate minutia a citable offense.

I would argue that someone driving around with 60 psi in tires that are supposed to be 33 is a smidgeon more than minutiae, since there is a real risk.
