After regarding through the posts regarding nitrogen in general, and inflation in particular, I am curious as to which type and/or brand of tire pressure gauge folks prefer.
I use a stick gauge. It is a Firestone gauge that someone posted a link to quite a while ago.
To check it's accuracy I compared it to a couple of the Technician's similar gauges when I was at my friendly neighborhood International dealer getting some service work done. All of the them read + - 1lb. when checked against a regulated air supply.
Nothing special used here; dial gauge purchased at a truck stop. I chose dial because it is easy to read without my reading glasses. Have checked it against gauges used in tire shops. It has been giving accurate readings for four years.
