Dually valve extender questions

[jayelldouble]

Just went through this with my 2016 Navion. For the first 6+ years of ownership I checked and adjusted tire pressures with double footed gauges/inflators and had no big problem doing that. Now that I'm 75 I find it tiresome but still doable. So I looked into getting a TPMS. First thing I found was that the TPMS systems require that the wheels have metal valve stems installed, otherwise the weight of the sensors will damage the rubber stems and cause leaks. And on the dually rear wheels the stems must be the type that curve out and around as there is no room to install TPMS sensors between the wheels. So I looked into getting the "dually valves" installed on my steel wheels. What I discovered was that the MB Steel wheels are (of course) different from everyone else's design and that as a result of MB's design the dually valves are extremely difficult to install in such a way that they do not leak and will stay in place for the long term. So long story somewhat short I now have 6 Alcoa aluminum wheels with the dually valves installed and a TPMS. A roughly $3000.00 investment but reading the TPMS rather than crawling around with a gauge is so much easier on the knees, back, etc. that I feel it is well worth it. I also have a warm fuzzy that a slow leak in a tire will not go unnoticed and I will be able to get it fixed before a catastrophic failure. Highly recommended if your budget allows.
