What I did was used tin snips to cut a slot (1/2" wide X 3/4" deep) in the chrome rim over the stem and then bent the cut down and back so the edge was rounded. That way I could see the stem and it was easier to attach and hold the truckers style air gage, or the fill up hose. This was all before I bought brass extensions. The kind you install when you're putting on new tires so they're part of the wheel. They don't go bad often. Cost $70 for two sets for the rear duals but they were well worth it. But they did need the cut in the chrome rim to make them more easily accessed too so it worked out well.
