I'm not sure of the exact volume, I don't keep it here at the house. I don't consider it small. It is about 2' in diameter and stands about 4' tall (tank and compressor). I think I've figured out an easier first step. I'm gonna make another quick connect fitting with an open flow lock on air chuck and a ball valve. If that doesn't do the trick then I'll step it up.

So pretty much what OldWrench suggested. I guess I'm not as creative as I thought.

Update for anyone that may come across this in the future. I just finished putting the slicks on for the track this wknd and ran into the same issue with the front not wanting to come out of the center channel. I was experimenting with different nozzles and found the perfect tool for the job. I put on a Moto D 90 degree valve stem (I've been told not to use a rubber 90 on high speed bikes, the Moto D is aluminum). Then used a standard blow gun fitting with the rubber tip removed. Also removed the valve core. Blew the bead in place in seconds.

I have an air chuck from Lowes. It does not need the valve in the stem to flow air and flows a lot of air. And that is the trick, not to have the valve in the stem. It is the trigger kind like this...

I tried the Milton Industries inflator that is almost identical to that. It doesn't require the valve core either but I wasn't getting enough air through it.

I always used q3s. They are a little suborn tire to mount. I dont use soap water its not slippery enough. Use a tire mount lube and fast fill air chuck. Ive seat the bead at 15 psi sometimes. Dunlop q3 has a hard bead to slip out of drop center. Good luck

I use the NoMar tire lube, it made a HUGE difference for me on mounting front tires. Soapy water should only be used for removal of a tire.

had the issue pop up on recent tires i slapped on the Raider. the dealer would not pump it higher than 50psi thinking the stupid thing would blow up..

Pretty damn silly if you ask me.. Rear tire is a 210/40R18, I asked around the local forum and several chimed in having dealt with it before and have
never had a tire blow up on them. I got some good advice from a close friend of mine and it worked like a charm.!

I just laid it in the sun both sides for a day then took it to the track (tire changer onsite), deflated, used no lube at all just removed the valve
stem so you can get more air in quicker and BAM, at about 63psi it just sealed like nothing. Try not to over-complicate your life, it just needs more air likely.

The sun will expand the air in the tire as it sits with say 40ish psi and allow the rubber to be a little more forgiving / flexible.

after I dropped pressure to 38psi and rode through end of summer without a single issue, this was on power cruiser so your required psi would be different of course.

yep! i had forgotten about this trick from my Trials days. Youre able to pump more air in at a higher rate! i'm pretty certain there's nothing wrong with the tire.

Lately I find a lot of people have their tires shipped in and they are tightly wrapped with plastic, you should take them out of the wrapper quickly
and lay in the sun prior to mounting, this will make things much easier in the future.
