Checking Tyre Pressures

[AdventureBoy]

I have just purchased a digital tyre pressure tester that can be carried with me on rides. I checked a few of the tyre pressures in the garage and got amazingly different readings. Most of the reading were lower than I antiscipated.

On a previous occation I checked the car pressure and drove to another garage and checked the pressure again, only to find a significant diference. I do not trust the garage gauges.

Does anyboby have a simple way of testing the accuracy of a gauge.
