Gas Coaches and air compressors

I have always used a 3 gal. tank 110v unit. Had a 12v unit but it took forever to raise a tire from 75 psi to 100 psi. because the cfm at 90 psi was pathetic. Be sure you get something that will deliver at least 3 cfm at your target pressure. Also, check to see that you can easily adjust the cut-in and cut-out pressures before you get one. You need to keep the cut-in above the target pressure for your tire.
