Dash TPM acuracy?
My hand gauge and dash don't match.
I have a pretty good (I think) analog hand gauge. Not the standard pen type. The dash gauge is about 3-5PSI higher.
Which should I trust?

My digital gauge (from the Tire Rack) matches the TPMS.

My Longacre tire gauge has a 3 lb difference too. I trust the Longacre.

I have never had a tire gauge that matched the TPMS. Even using the same tire gauge many times it never matches the TPMS. Moreover, I have numerous other tire gauges that do not match each other or the TPMS.

My TPMS readings on the dash are always 3 - 5 lbs. lower than my digital tire gauge. The same was true for my 997.
For what it’s worth, the readings on my GMC Denali truck match the tire gauge.
