Air pressure gauge

RE- the Joe's link-

What good is a tire gauge that only goes to 30 psi?
I want a Guage with the sweep emphasizing the range I run my tires in.
I have a hundred pound gauge, that's okay, for the truck and rv tires, a thirty pound gauge thats pretty good, for drag radials (run normally around 18-22lbs,) and my big quality gauge that I've had for 25 years, that's 0-15 lbs. ( Run ten inch slicks around 10-12, 14 inch slicks 6-8. Lbs). Hundred pound gauge ain't much good when I'm trying for the difference between 6 1/4 and 6 1/2 pounds......
