<VV> Tire Pressure gauge reccomendations wanted

[Frank DuVal]

The "Best" tire gage I ever had was a used pressure gage 3" in diameter, 
1/4" npt back fitting, with a full scale reading of 60 psig. I screwed a 
Milton 691 straight chuck onto the 1/4" npt fitting. You had to hold it 
on the tire's schrader valve, but it sealed well and seemed accurate. 
You could see the reading very well.

Most any of the Milton tire gages have worked well for me.

IIRC, the tire pressure will change 1 psig for every 10 degrees F change 
in temperature of the tire. So if the tire is run and warms up 30 
degrees, the pressure rises 3 psig.
