    Default Digital or Mechanical Tire Gauge?

    OK here is a question that I haven't found an answer to. I always had a mechanical tire gauge and it seems to be working fine. Recently I bought a digital tire gauge. The digital gauge shows my tire is 4 to 6 pds more inflated than the mechanical one.. My OCD is kicking in and I need to know which one is accurate or close to it. Maybe y'all have had the same issue?

    Don't try to figure this out. The digital is going to be more accurate. All the gages in my shop are off by at least 3psi. My pen style gage is high by one according to my digital.

    X2 for me as well i have used both and they are all off a bit. The whole point of most of your off the shelf ones are just to get you to the point where you arent low....

    Go to a tire shop, and ask them to check your tire pressures, then check them with your gauges and compare Just because it is digital does not make it more accurate either.

    The digital should be more accurate. Where I work we have a calibration gauge. it is digital and it is accurate to .1 psi.
