@EAST - I use an inexpensive Victor 2250879V Digital Tire Pressure Gauge which has a +/- 1 psi accuracy and is spot-on accurate with my local Discount Tire store's air pressure equipment as well as data derived from the TPMS sensors using Carista OBD2. TPMS sensors generally average a percentage difference between displayed and actual tire pressure of only 1.2% to -1.5%. But even at a large percentage difference of [say] 3.5%, that only reflects 1 psi difference for a tire inflated to ~35 psi which is the recommended tire pressure we typically run.

I'm happy knowing my tires' air pressure is within 1 psi of what I measure using this accurate little digital tire pressure gauge. I'm OCD about liking to maintain all four tires with the same amount of air pressure.

I keep a handy little in my tool chest and one in my console.
