For customers looking to use a Crossfire Pressure Equalization System by Dual Dynamics with their TireMinder TPMS, TireMinder customer Dale in Maricopa, AZ has offered us some great insight.
“…I now agree the Tire Minder will NOT work properly if connected to a single valve. It would read a pressure – let’s say 90 psi in my case.
The orifices' in the Crossfire between the two tires are very small. The tires will equalize with a small difference of pressure and the safety valve between the two orifices' will not close off. But if a blow out were to occur, the pressure difference would slam that safety valve closed almost instantly. One tire would go to zero and the other might drop to 89 – if even that.
So if there were only one tire minder, Tire Minder would think everything was ok, possibly show a small leak. With two Tire Minders, the blow out would alarm almost instantly.
The additional cost for the two extra stainless valves was only about $25 per set of tires ($50 total). The additional Tire Minder transmitter are $40 each. Why not do it right?”
In summary, yes, the Crossfire Pressure Equalization System can be used with your TireMinder TPMS, however it is recommended to place 2 transmitters before the safety valve.
