I used to have one that was rated for 60 pounds but now we bought a trailer and it takes 65 pounds of air in the tires. Instead of typing in 60psi and adding more air for say 5 seconds, I bought one that reads 65psi. Used it once and am as happy with it as I was with the 60psi gauge. They are easy to place on the valve stem and read. I expect it to be the same as what I have. Good tools.
