Question:
I plan to add tire pressure monitors to my rv wheels but need to turn the valve extenders on the outer wheels on the rear axle. I think that simply loosening the retaining nut, turn and retighten should do. But is it OK to do under normal pressure -100 psi?

Will this damage any washer causing a leak or..........?

Tx Dennis S. Peacock

PS do you have a recommendation for a monitor unit?

Answer:
Hello Dennis,
 
I believe you should be able to loosen and rotate valve stems without hurting anything as long as you have no sticky or damaged parts . Try loosening and rotating  the stem the direction you need it to go. Check for leaks after you install monitors by spraying a soapy water solution around the attaching points on the stems and pressure monitors.  A real common one we have sold is the Pressure Pro brand .  To install simply remove the valve caps and screw the new monitors on. It will give you a pressure only reading.
 
There is another brand on the market  that goes inside your tires and is mounted  with a big stainless steel band to attach  around the wheels.  It measures temperature as well as pressure.    
Here is the info on  the SmarTire System:

Sensors mounted on each wheel measure tire pressure and temperature every 12 seconds and wirelessly transmit tire data every three to five minutes to a receiver mounted on the vehicle.

The receiver then processes the data transmissions and compares them to pre-programmed settings to determine if a tire is under-inflated. The SmarTire RV receiver can monitor up to 20 wheel positions and is able to handle RVs of any length and tow-behind vehicles.

At the push of a button, real-time tire pressure and temperature information is then available to the driver via a dash mounted display. If the system detects a tire that is operating under-inflated or extremely hot, the system automatically warns the driver to the condition before it becomes dangerous.

Here is the install info I can share with you on the SmarTire as well.  
Those monitoring tires on an RV or towing a large trailer with a SmarTire system will have an advanced installation.
·  First, have your local tire professional remove your tires from your wheels. ·  Then you or your installer will install the wireless sensors on your wheels using the included mounting straps. ·  Next you will need to run one or more external antennas under your vehicle for extended wireless range. The antennas mount magnetically so no drilling or bolting-on is required. ·  The SmarTire receiver or display is as easy to install as a radar detector; just choose a spot to mount it and then hardwire it to a switched power circuit in your vehicle.

There are other companies as well besides these and I will be looking into them soon, however I wanted to get back to you now.

Best wishes and  Safer & Happy Driving,
