i have a 5 gallon tank with a large electric compressor, its mainly for my air horns but also for 4 wheeling, small air tools etc.

the other night i was trying to fill a car tire to 45psi, well being my compressor kicks on at 110psi, and off at 150psi, i figure it would be no problem. my set-up would not inflate the tire tho. id get a good 5-6 seconds of air blowing into the tire then it would die, even tho the tank still had more than 110psi in it and the compressor was not kicking on.

do i just not have the volume to fill the tire or is there something else wrong in this case

ive got a similar setup. its about volume, not pressure. I need another tank, i want to be able to run a impact off of mine, and right now it will take off one nut, then i have to wait for it to build up again.

So i think another tank would help a bit. might try it.

How do you know the tank had 110psi?? Only because the compressor wasn't kicking on?? Might be a pressure switch problem... 5 gallon tank, car tire, 110-150psi should be no prob

ill throw a gauge in the extra port and test it this week and see if i can find the out if its draining the tank too quick or something

It really shouldn't be a question of volume unless you are fixing a completely flat tire and then the comperssor might have to cycle. The air should not stop flowing until the tire is at the same pressure as the tank. Meaning, if your compressor kicks in a 110 it should definitely cycle unless you've got the tire up to 110 lbs (unlikely ).

A 5 gallon air tank at 110 psi has more than enough volume amd more importantly pressure to fill the average sized car tire. If you split the difference and fill the tire until it equals out you should have close to 50+ psi in the tire.

Are you sure the shrader valve in the car tire wasnt messed up causing the flow to be blocked? that sounds like what was going on here.
