Getting annoyed airing up tires.

[Chamberpains]

Way over thinking it. A simple Lockon dual air chuck will solve you delicate hand problem. Clip it on the tire and let it go. Your truck will air a tire up from 0 psi all the way up to 110 psi in 15 min or less. My truck cuts out at 130 psi and when I leave the truck hose clipped on for a long time, the max psi it'll inflate a tire is 110. Perfect for your desired pressure. If your truck only builds to 120 psi you can adjust that at your air governor on the compressor.

If your inflating at home you may want to look into a larger volume air compressor. I use a 60 gallon (I'd like an 80 but i bought it 15 years ago before trucking) and I had to break the regulator seal and turn its max psi up from 120 to 130. Now I can inflate my trailer and steers to 120.
