I am also considering adding a tire pressure monitoring system. All comments are welcome. It is virgin territory for me.
I use rigid valve extensions that I picked up at my Airstream dealer (they sell all manner of accessories, not just Airstream-specific). I forget the brand name. The straight extensions for the inner tires are about 4" long. The J-shaped extensions for the outer tires are not quite long enough by themselves, so I added 4" straight extensions to the J-shaped extensions as well.
I also got a 3-foot-long flexible extension for the spare, with the end of it fastened to the underside of the rear bumper, so I can check the air in my spare— and pump it up if necessary— without crawling underneath or cranking down the spare.
The rims do not take replacement valves with built-in TPMS. TPMS on the valve caps is not terribly practical on the valve extensions, either. However, there was a write-up in this month's Motorhome
magazine, about a TPMS that attaches to the rim inside the tire, with a band that wraps all the way around the rim. The company is Valor TPMS (Valor TPMS
), and one thing that I find interesting is that I can also get these inside-the-tire sensors added to the rims on my Honda toad without getting rid of the Honda's own TPMS. That would let me monitor the Honda's tires as well when it's hitched up. Having already had a blowout on my Honda while towing it, that's even more important to me than monitoring the Interstate's tires. I haven't contacted them for pricing yet; I just read the article yesterday.
