Just curious. Over the years I have accumulated (my wife would say "hoarded") a number of the "pencil shaped" pressure gages and a few of the digital ones.
My experience is that I can use any one of them and get a different reading - within probably a 2 pound range.
Concern is - when you are in the desired 15-17# range for your tire pressures, a 2 # difference is a lot

So does anyone know of a tire gage that is "very accurate" in this range
