Looking for thoughts and considerations for an AIAir 4000P 12V air compressor capability to air 22.5" tires on a Class A motorhome. All information and comments will be appreciated
Why not just go to a 110V compressor? This Porter Cable produces 2.0 cfm at 90 psi and 3.0 cfm at 40 psi, whereas your Viair 400P only produces 1.28 cfm at 90 psi and 1.75 cfm at 40 psi. Those big tires take a lot of volume in addition to pressure.
