I'm looking for a new semi-portable air compressor for various purposes.

Here's a spec for the models I am considering.


CFM/PSI 3.6@100 3.8@100 4.5@100


Let's say I have a tire on a 17" wheel to fill to 55 psi.

What is the approximate time it will take each of these compressors to
fill the tire, everything else being equal?

Is there a formula?

Thanks (English major here)

Harry, I have a 2.9 cfm at 90 psi, with no tank (an el cheapo from Sears)
that I use only for tires and soccer balls. It takes me about 30 seconds to
raise the tire pressure from 25 to 35 psi on my pickup.
