Thanks for writing. I suggest you use a digital tire pressure gauge. Stick or “pencil-type” gauges are not very accurate and while dial gauges are usually better, digital can show pressure within 0.1 PSI, allowing the user to get all of the tires equally inflated.
Digital tire pressure gauges are now relatively inexpensive and easier to use than other types you mentioned. The tire pressure sensors are relatively accurate as they have to adhere to Federal law and trigger the TPMS warning light when the pressure drops 8 PSI below the door placard pressure.
