Need advice do I need to replace the factory valve stems in order to install a tire pressure monitoring system on my 2017coachman 26rs

Thanks to all

What does the manufacturer say? When I installed my system including sensors on the dolly I replaced all of the rubber stems with brass per the manufacturer. Since the dolly was the only place that had rubber stems the replacement was easy. On the coach I put the sensors for the inside rears on the end of the extender lines but mounted them to the wheel covers. If your stems are rubber I suggest installing the brass or metal stems.

Call Your Tire Shop Supply, Duallyvalve Kits for Class C - Ford GMC 16-19.5". They are great and after a few questions to make sure of your needs will send you exactly what you need. I love my stems makes checking air and airing up so easy and very sturdy to support TPMS. I chose a TireMinder 66 system.

When I first got my trailer (since moved on to a Class C) I had new tires put on to replace the China bombs that came from the factory. At that time I had metal stems installed. This served two purposes. First, it made the stem very rigid thereby reducing the likelihood of a failure due to a rubber stem failing. Second, with my TPMS (from TST), I can measure both pressure and temperature, so the metal stem transmits rim temperature to the TPMS device much better than a rubber stem would.

I use the same TPMS on my current Class C, but that MH came from the factory with better tires and metal stems.

I believe your new rig has rear duals. That being said, it is nearly impossible to get a TPMS sensor on the existing stem on the outside dual, since it ends up between the rear duals. Like mentioned earlier, I put Borg Dually Valve Stems on my rig. Bought direct from them - then discovered Camping World (of all places...) actually sells the same item for less. Also changed stems on fronts to metal, long enough to reach thru the wheels simulators/covers, so I could use the TPMS sensors on them, too. According to TST (makers of my TPMS - very pleased with them), unless you have the flow-thru sensors, you do not *need* metal stems. Case in point - toad has rubber stems since it has internal OEM TPMS - but added TST sensors to them externally without issue. ST
