Sometimes my wife accuses me of being too negative because I seem to always come up with something negative about almost any topic. I really don't consider it negative when I see there might be a way to make something or a situation better.
I guess it's in my DNA to never be satisfied and always want things to be better, easier, safer or more durable.
The simple act of checking tire air pressure is an example.
Each time you use a hand gauge to check air (morning of every travel day) you are pushing on the valve stem. If you have a standard short (less than 2") valve stem, no problem, BUT for dual tire positions as seen on almost all Class-A and Class-C RV motorhomes there are either valve stems that have a bend in them or there are extenders of some type. Pushing on a bent or angled stem will place a torque on the stem mount in the wheel. This can lead to eventual degradation of the rubber seal between the wheel and the stem. Here is what happened a few years ago to the tire of a friend of mine. He was not running a TPMS so got no warning that the valve stem developed a leak at the rubber gasket between the wheel and the stem.
The tire lost air and the steel body cords fatigued due to over-flexing of the sidewall which resulted in the sidewall "blowing out". Initially he thought it might be a "defective tire" but when inflating the new tire it was discovered that the valve stem no longer had a solid rubber gasket at the wheel. So obviously this was not a "defective tire" as any tire can fail if you do not keep the air in it. Soon after this he installed a TPMS.
If you have some type of extenders, flexible hose or hard line, you might end up moving or bending re even loosening the extender if it isn't supported when you push a gauge or air chuck on the outer end.
One advantage of running TPMS that
few people consider is that the TPMS gives you a pressure check each
morning, as well as continuous as you drive down the road so this eliminates the need to push on the stem or extender.
No Muss or Fuss and the additional benefit of no torquing the valve stem mount.
