Bummer..... I just thought of something... it may be worth the
nitrogen to protect those TMPS sensors...

Most of the TMPS systems don't really measure tire pressure.
The system has speed sensors on each wheel and measures the rotation time of
each tire compared to the others. If a tire is low, it's number of
rotations for a given speed, compared to the other tires will increase.
That's what triggers the low pressure warning.

It's a natural add-on capability brought about by anti-lock braking systems
(which require the speed sensors).

So, air or nitrogen means diddily.
