Question about TPMS

[Tinstar]

Regarding TPMS; On the rear, what do ya'll do about the inside dually. Mine has pretty short stems and I can't get my hand in the holes on the outside rim. I know I can remove the outside and have longer stems put on, but is there an alternative. Are folks successfully using extenders? That makes for a lot of connections: stem, extender then TPMS.

Valve extensions will leak and fail-- but now, you will have a TPMS to tell you that . Spend the extra time to get properly configured metal valve stems.

When you have your RV in for new tires, or in for service, discuss your needs with the shop and explain what you want. There is no need to have to struggle with the inside dual when there are so many different valve stems available. Using the right valve stem will allow you to install a TPMS sensor or just inflate your inside dual. DO NOT just accept it when a "mechanic" installs inaccessible valve stems on your wheels.
Here is a picture of just SOME of the different shapes that are available. There are many many more that will give you access WITHOUT valve stem extensions.
