Anyone think those are a money saving devices? I just learned that
the sensors in tires should be replaced every time you buy tires and
they are over 40 bucks per tire.

The cost would seem to outweigh any savings from preventing any
improper tire wear.

"Money saving?" for a passenger vehicle? No, not really unless one paid
no attention otherwise it's possible. They are a safety feature that is
worthwhile imo; again if paid attention to when indicate low pressure.

So just ignore over inflated?

Well, DOH!, no, but it's far less of an occurrence other than perhaps
after a flat repair or the like. Plus, in general most current
passenger tires are rated for 40 or so psi as max and they'll actually
run cooler (albeit harsher ride) at the higher pressures so it's pretty
unlikely to ever have one high enough to actually be a real concern...

Possible, sure, but not very likely particularly in comparison to
under-inflated which is both more likely from starting at low
recommended pressures with any leakage and that low pressure equates to
more sidewall flexure which is more heat which is the real culprit in
causing failures at speed. There's secondary contributor to
excessive/uneven treadwear of course.

The pressure in tires rarely increases by itself. ;-)

Then how come in NASCAR they start out with really low tire pressures at
the start of the race or after a pit stop to allow for the pressures to
build up?
