Tire Pressure accuracy

[GRNMSTA]

Hi folks. In my 20 Bullitt, the readout in digital dash is showing tires at 35-36, yet two analog guages show 30-31. Anyone else seeing this? Is there a way to calibrate? Thanks!

Make sure your ambient gauges aren’t dime store trash, and make aure the tpms sensors are actually updating and not showing a stale reading.

Usually my sensors are within 1-3psi of my Longacre gauge. There’s no way to calibrate them. 5-6 psi difference is not typical IMHO.
