From time to time this subject has come up.

I had an interesting? thought. Why doesn't someone come out with a gauge
that you push against the side of the tire that measures the deflection?
Beats removing a cap and fooling with a fussy tire air pressure gauge. It
might need to be calibrated by the user with a regular gauge depending on
type of tire. I'd buy one (if it didn't cost an arm and a leg).

What do you think?

Deflection is not the way to measure. Is the fuel tank empty or full? Driver
inside or out? On a stone or flat surface? Buy a dial type with hose and
don't drop it. Or digital.

Hmm,
Our cars came with TPMS. When replacing tire, they can be reused with
a kit which basically new valve seal, nut, washer.

They only last about 5-7 years though :/ Already replaced two on my 2009 MY car.
