The Altima I drive now has a cool feature. If you leave the ignition on
(but engine off) when adding air to a tire, the car horn will beep when
the tire is at 32 psi. Don't need a tire gauge.

I am not convinced these things are that accurate.

It's not spot on accuracy I worry about. It's losing 10-20 lbs rapidly, or the temperature
increasing rapidly that worries me. I like the idea of a warning alarm when either occurs.

That is what the sensor is meant to do. I still want to use a real
gauge to inflate them.

I checked the readings given by my car display with a dial type gauge
that I have used for years. It's a fairly expensive one that holds the
reading until you push a button on the side to release the pressure
within the gauge.

Anyway, dead nuts with the Nissan system readings as near as I can tell.
The Nissan display reads in 10ths of a psi. Can't resolve it that well
with the expensive dial gauge.

I am just relating my experience with whatever Ford was buying some
years ago.

Actually, I fu'ked up. It doesn't display in tenths. I must have been
thinking of the average fuel mileage display.

I just took a ride to the store and put the dashboard display on the
tire pressures. It shows a graphic of a car frame and all four tires
and their pressures. When I left the driveway they were reading 32, 32,
32 and 31. The 31 reading came up to 32 within about 2 miles. Within 5
miles they were all reading 33 psi.
