The Tire Pressure Monitor Story

Maybe I’m just paranoid, but the thought of driving a large dual-rear-wheeled vehicle without being able to monitor the tire pressure seems dangerous to me.

Even with single rear wheels, I’d like to be able to monitor them and perhaps get some advanced warning of a tire issue. But with dual rear wheels, my expectation is that one rear tire could have quite severe problems without it being obvious to the driver.

This obviously leads to installing an aftrmarket Tire Pressure Monitor (TPM) system. The system I bought is an EezTire system which uses the small senders that screw onto each tires valvestem.

Installation of these did not go well. The front tires were fine, but the rear tires were another story. The valvestem on the outer tired faced inwards. The valvestem on the inner tire was unreachable via human hands. They were prefectly fine for checking and airing up using an extended chuck, but no way were the TPM senders being screwed on.

So on to the next step. This was calling around the various tire places trying to find one that could add extensions. Fortunately we were able to find one that could do it and get us in before we had to start our trip back to the west coast. About $120 later we had flexible extensions added that allowed me to screw the senders on.

Now there is a lot of discussion on the internet in various groups and forums about the various types of valve extensions. The best option seems to be having the existing valvestems replaced with solid metal extensions. For expediency we went with the flexible ones. I gather I’ll need to special order the solid versions, assuming they are even available for the Transit. That is the eventual plan, as I’m a bit concerned about the long-term reliability of the flexible extensions. If nothing else, just having more connections is more places for leaks to occcur.

The TPM itself worked *great*. Was really nice to be able to see the tire pressures as we cruised down the highway. It was also very convenient to turn the monitor on in the morning and see that the tires were ok before hitting the road. And without needed to use the guage on each one!

It would be great if WGO could somehow make a TPM system a factory option. Mine has already cost several hundred dollars, and to avoid the stress, time, and effort it’s required I’d have been happy to pay hundreds more to have had it already installed when we took delivery of our Paseo.

Why isn’t this a standard feature? Apparently vehicles above 10,000 lbs are not required to have a TPM system, so the Paseo does not. (Versus say the Travato, which does have one standard.)
