I don't trust digital gauges.. I have a 40 year old Campbell-Hausfeld attachment on my air compressor I use to add air to my tires, it has a gauge on it but l use a Milton S925 pencil type tire gauge to set the pressure. My TPMS on the suv is off about 2 pounds off the Miltons reading. Every time I get service done at the dealership.. my tires are at 40 psi.or higher. norm is 34 psi..none of them need batteries...
Project Farm, here on RUclips, did detailed testing on tire gauges. Highly recommended.
Yes, it is a great guide to tire gauges
