That way the wheel could be mounted valve-down and you'd be able to check the pressures more conveniently. I'm imagining modifying the cap to one that's much bigger in diameter and a lot deeper, to cover the entire stem. Maybe it could have a flat flange on top so you can easily twist it off with your thumb and index finger (think of a rad drain plug). And you'd design the threads so if the thing were ever overtorqued, the threads would just skip over each other. Since the cap would be bigger in diameter, the mud buildup would end up with a large hole in it after cap removal, so you could easily get a pump and pressure gauge on the valve. -- Tegger

The other idea I've seen is an extension hose that attaches to the valve stem, with a Schrader valve on the other end so you can check pressure and add air as necessary, although it seems like this setup would be prone to leaks. -- Ray O (correct punctuation to reply)

Here's what I'm imagining... <http://www.tegger.com/hondafaq/misc/cap-idea.gif> Would be a LOT cheaper than the extension hose idea, once you got past the mold cost. -- Tegger
