Air compressor will it work?
Someone in my naborhood is selling a Air compressor for $200 the model #IRL6560V it's A CHARGE AIR PRO 125 psi 60gal will it work on my rv tire that holds 120psi?

J&R I do have a onboard compressor that goes to 120. but I have never tried it because I had a 30gal 135psi and it wouldn't do the job? this one I am looking at has 15.2 CFM 13.SCFM @40PSI AND 10.5 @ 90PSI Not sure what all that means?. 240v 6.5 hp.. 60gal. I didn't think one of them pancakes 150psi would do it because of the tank being so small.
For filling tires, the tank size makes about zero difference, and the flow rate (well, after a point at least) not much difference. The flow is more limited by the tire valve than what the compressor is capable of pushing out. (That's the SCFM @ PSI ratings: standard cubic feet per minute at whatever pressure. Many air tools use 90 psi, and varying amounts of air. If the tool requires more than 10.5 SCFM, the compressor won't be able to keep up with continuous usage, though you can get decent bursts of use due to the air stored in the tank.)
If you're actually trying to inflate your tires above maybe 100psi or so, the difference in pressure will make a very real difference in how fast the last bit goes. A 5 psi difference (between 120 psi in the tire and 125 in the compressor tank) doesn't lead to much airflow into the tire, while a 15 psi difference would be a lot less slow--but still not super quick.
