When I post, I always feel like I’m at a meeting, “ Hi, my name is Dave and I’m a newbie. I’ve been RV’ing for 1 week...”. Any way, today’s adventure is installing a TPMS system on my RV and tow vehicle. 10 tires in all. I bought the TST pass through system. I’m familiar with 3rd party TPMS, as I have them on my motorcycle. Programming of the 10 sensors went fine. Installation was where I found the challenge. I’ve never had a vehicle with dual back tires, so I had no idea how the stems worked. I expected one to come out to the outside and the other the inside. I was so wrong. On my vehicle, The inside tire stem has a flexible extension on it and it comes through the outside tire rim. Very convenient. However the outside tire stem can be seen under the rim pointing toward the inside tire. I’ve attached a picture. My questions are, how do you even get a tire gauge on that tire stem to get the air pressure, let alone attach a TPMS monitor to it? Is this the standard configuration for dual tires or are mine out of whack?
