What tire gauge do you use?

[Lowes48fan1]

I checked my trailer tire pressure using three different gauges and got three different figures. Two were the pen type where the plastic gauge extends out the end and the other was one that had a round dial.

Obviously they couldn't all be accurate. What do you use and how can you benchmark it for accuracy?

I use a Slime digital from Auto Zone.

Quick easy and it is rated to 150 PSI.

Running 80 in both the truck and trailer tires as per the sidewall.

I use one of the pen types for trucks. I think it reads to 110 psi. I've used several and they were give or take 2 lbs difference. Close enough. I checked mine up against a car with TPMS on it. They were fairly close.

I use a pen type for trucks as well. I'll see about testing it against something that has TPMS. I hadn't thought of that as a way to check the accuracy.

Thanks!
