So I just bought a nice Milton tire pressure gauge (dad always said if it not a Milton, it's trash). Anyways, the Milton gauge reads 35 and my TPMS monitor reads 40 (for all tires). Anyone else come across a TPMS discrepancy? PROBLEM SOLVED. Old guy can't read gauge.

Nope. I have an ARB inflator and it indicates almost exactly what the TPMS is reporting

Have also confirmed this on my partners car (Hyundai) and it also matches that TPMS too

My numbers are closely matching (maybe 1-2psi off tops). As you probably know, check PSI with cold tires that haven’t been driven on and average ambient temperature.

Nevermind. I was reading the gauge incorrectly. Low light in the garage plus old eyes. Gauge pressure matches TPMS pressure. Thanks!
I feel your pain ?. I run mine 34-36psi and seem like a good spot. Enjoy your truck !

I concur. Among different brands of digital tire pressure gauge, ARB is the only one that is right on the mark with TPMS.
