airing up tires

[diesel lover]

Im a full time truck mechanic. I have to air up the tires on almost everything I pull in at my new job. I was wondering if it would work if I hooked up a regulator and could adjust it as needed. For example drive/ trailer tires need to be aired up to 100 psi. What if I installed a regulator inline and had it adjusted to 110 psi? That way the max the tire could inflate to would be 105 psi or so. I don't mind airing up tires but our shop air pressure is 150 to 165 psi, if your waiting for the tire to air up its not hard to over inflate the tire.

In theory the regulator would work, but would it really work? This way I could do other things at the same time. Yes I do have an inflation gauge attached to an air chuck, but this is only ok for one or two tires. If all the tires are low I have to stand there and hold the lever, as compared to hooking the air chuck to the tire, giving the tire one minute to 1.5 minutes and checking the tire pressure again. Thanks

I did about the same thing on an electric compressor, but used a pressure switch on the compressor, not a regulator. That way there was no air in the system at too high a pressure.

I don't see why it wouldn't work, as long as the gauge on the regulator was accurate. The only thing I would say is wrong, is that if you set regulator to 110 and leave it attached indefinitely, you will have 110 psi in the tire... assuming an air-tight connection at the valve.

This brings up another question though. The Milton inflators with the lever and gauge tell you not to use with locking chuck, anyone know why?

Glad to read that you have found a new job!!!

I tried it once and it failed. It was a cheap Chinese inline regulator. The tire was a military surplus 9.00x20 NDT, 80 psi max. Inline regulator was set to 50 psi, the Ingersoll-Rand regulator on the air compressor was 110 psi. I about pooped my pants when I saw the inline regulator near the tire reading 110 psi.
