On my new dually, it has metal valve stems, bent to face inside, on the outside rear tires and on the inside, it has a plastic extender on the valve stem. The tool I usually fill tires with is one of those slightly angled head ones that allows you to pull it onto the stems that point backwards, or push it onto stems that point out. However, for the inside tires I have to put the tool though a small hole in the outside wheel to reach the inside tire. It's hit or miss if I make a tight seal so the built-in gauge will read properly while I'm fill the tire. I tried a Milton Industries s516 Inflator Gage because it has a straight on and angles head, but it will not work on the plastic extender of the inside wheel and it seems to have threads that will not let it slide onto metal valve stems.

Anyone have a solution?
