I use rigid valve extenders. The ones for the inner tires are straight. The ones for the outer tires have a J shape, so they face out, too. That lets me air up anywhere.

I also added a "spare air" extension hose for my spare tire, that lets me check the pressure and inflate as necessary without crawling underneath. I attached it to the bumper on the passenger side.

These do not leak on mine. However, even with valve stems that do not leak, your tires can be expected to lose anywhere from 2~5 psi per month. So it may be worthwhile to invest in a portable compressor as well. You'll also find a compressor useful when you need to blow out your water lines for winterizing. Here's the kind I have:
