TPMS...Accurate Pressures?

[galaxy]

Do you guys use the numbers on the dash for tire pressure, or use your gauge? I have a gauge that I trust (verified against other quality tire gauges at a shop), and I checked tires yesterday...the dash reads ~4 lbs higher than my gauge.

Curious what you guys have seen for accuracies.

Mine are within 1 lb across all 16 of my tires. I have four sets - snow, street, track wet and track dry. TPMS is very accurate in my experience. I use it on track to see if my tires are at target pressure.

Mine read the same as a manual gauge. From my experience with TPM systems that give a number readout, they're pretty much dead on the money.

My gage panel reads the same as my digital tire pressure gage.

I don't have a GT-350, but my TPMS ('16 Edge Sport) and my wife's TPMS (Hyundai Tucson) are very accurate. I've never found any noticeable difference in air pressure between the dash display and my gauge.
