I have the TireMinder TM77 pressure monitoring system and am getting ready to install the transmitters the rear duals. To catch the outside tires (which are mounted with the valve stems on the inside)...
I have mine on a braided extension off the 135° valve extender and affixed to the hub. I've already had one leak in that configuration, so I would think the centrifugal force will be too much with the transmitter hanging off the extender.
