You do know Davy Crockett killed him a bar when he was only three?
Mine are never that close. Usually the 2-3 pound spread, have no idea what accuracy, precision, standard deviation, coefficient of variation, or reproducibility Ford assigns to their TPMS systems. But then I don’t know that about my pressure gauges😀
I wish that Congess would repeal both Charles’ law.and Boyles’ law.
These.laws relate temperature, pressure, and volume. Repealing these.laws would keep the tire pressure from increasing.when the tires are warm and decreasing when the tires are cold.
Does this meet the criteria for. boring knowledge?

I was only being satirical with the title of this thread. I find knowledge to be neither of the above (boring or nerdy).
Don Imus employed satire whenever that red light was on over the studio door. He did not consider those basketball players to be “n a p py - headed ….(whatever term he employed back in 2007)”.
He was ridiculing those that felt that way, and or used those terms in daily speech. Millions of even his diehard listeners missed out on that subtlety, or probably picked up on it after it was too late.
I find Charles Law and Boyles Law to be quite Ideal.

Congress enacted Charles’ law and Boyles’ law because people wanted air conditioning and heat pumps. These.laws are ideal for these applications.
Not hard to do, if needed, just over inflate by a little bit and then air them back down to the proper psi…

I more or less do do that. But usually only by a few tenths. Maybe I will try going to 35 PSI or more then drop it down to 32.3, remember the 0.3 is to allow for pressure lost when removing the chuck.
I suspect the variation is in the TPMS, not in the tires. Like does the system round up and down, or does it ignore tenths of a pound, or are the sending units not that precise. I just might hook up my scanner (Blue Driver) and see what it shows. Not even sure if it shows tire pressure.

The data in the TPMS module is displayed in tenths or hundredths of a pound. Variation between sensors is very small, less than 0.3 psi.
Dash readout is in whole numbers.
I view both displays when servicing vehicles. To display tire pressure in tenths of a pound on the instrument panel would be a distraction for the driver and a cause for complaint: “My tire pressures are uneven”.

Ask your congressmen if they can do you a solid on this one. See what happens.

They might not even know what Boyle’s law is. Most legislators, as well as the mass media, honestly believe they can add more sunshine by turning the hands on a clock.
