I have used a round dial press gauge for my tires for years and it finally failed with incorrect and varying readouts. In the past would put in pressure then check and go back and forth until I get the pressure I wanted. This time I ordered a fill and gauge in one and dang it is so much better. I recommend this to everyone who fills His own tires. Lots of choices out there but I wanted a 0-100 and American made. This one is perfect: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
