How to inflate to 110 psi....

OK, I know it sounds stupid, but I am unable to add air to my tires using the aux air connection from the MH. I need 110psi, but I think the cut-in/cut-out psi will not allow me to add air as the pressure is not high enough in the MH. Maybe I need to give it more time, but how long does it take any of you to add 6 lbs of pressure (to go from 104 psi to 110 psi),

How do you guys add air to your tires that need 110 psi? I have even tried a separate compressor that is suppose to go to 125 psi, but I can't get any air into them using that. Do I need to buy a separate larger compressor? As a newbie, this is one challenge I did not expect.

Thanks, Tom

    Are you SURE you're not getting air in? Do you have a gauge on the dash or compressor? When there is only a 10psi difference it's going to take awhile. And you won't hear it like you do dumping air into a 30psi tire with 120psi at the compressor. Hopefully yours clamps on the valve, because that's allot of volume to fill slowly

    I'm able to get 110 using the on board compressor. It helps to have a second person in the driver's seat watching the air pressure telling you when to stop airing and to apply the brakes to get the compressor to start pumping. When the pressure gets to 110 you start airing until it drops back to 110. Then applying the brakes several times to get the compressor to start pumping at high idle and usually two cycles will do it. Since it's the front tires and I have a chuck that stays on I do it by myself.
