I have a crossfire, I can not install it (at least not by myself)
Advantages of Crossfire: It keeps the pressure in the dual pair equal, at least to a point, that point is a cut off pressure, if pressure in a tire drops below that point (note, baring a suddenl blow out both tires will drop together) a valve slams shut and prevents the other tire from going fully flat.
It has an EYE so you can visually check your pressure at a glance (read on)
And it makes it a whole lot easier to add air to the tires (Why I bought it) as it functions as a valve extender
Disadvantages... If one tire goes flat, the other goes very low, You have to actually LOOK at that indicator eye Only monitors duals
Pressure pro,
Disadvantages: Does nothing for pressure equalizaiton, and does not make it easier (or harder) to add air if needed
Advantages: Monitors ALL tires, motor home and towed or truck and trailer or if you like Tractor and trailer, can even monitor the spare if you wish.
Easily moved from Tractor to Trailer (Motor home to towed) if you are operating seperated, can, at the user's selection, monitor one (Either one) or both vehicles. Automatically checks the tires about every five minutes and alerts if the pressure drops a set percentage (I think it's either 10 or 12%) and alarms if the tire pressure has dropped. No need to "keep an eye on it" it does that for you.
MONITORS TOWED and monitors ALL TIRES
Easy to install (As easy as checking tire pressure the traditional way)
Advantages of Smart Tire, Like pressure pro it can monitor all tires, and alarm if pressure drops, also monitors rim temp (tire temp) and will alert for both over and under conditions.
Disadvantage, Hard to install (requires professinal instalation) won't fit on some toweds and you can not move it from towing to towed if you wish to operate vehjicles seperated (IE: when camped)
Oh yes, I mentioned I have a crossfire I can't install.. I also have Pressure Pro, the two can be used together
