Aluminum air tanks, what kind of PSI you guys running??

Just wondering how safe with would be to run a 145on 180off pressure switch on a aluminum tank only rated for 150psi?! School me!

i run 200psi

I run mine to 200psi everday.

I have 2 3-Gallon tanks, and I run them at 200psi. DOT law states air tanks are to be rated at 150psi, but they can hold more pressure than stated on the product. Just make sure not to overdo it.
