Crossfire Dual Tire Pressure Equalization System, 100 PSI, one per pkg. (CF100STABT)

Reads the pressure easily .

Overall happy with the dual tire monitor system. Installed this on a motorhome with 22.5 inner steel and outer Alcoa aluminum wheels. Pressure readings via the colored flag are very close to actual pressures. Installation was simple but I have aluminum Alcoa outer wheels and the supplied bracketto allow use of the lug nut for mounting is too thick for use with these type wheels with standard wheel studs so the lug nut holding the bracket to the wheel stud barely engages all the threads. When I locate them I will be installing at least one longer inner wheel nut so the outer wheel nut will engage properly. One item to keep in mind is not to over tighten the hose connection to the valve stem or valve stem extensions and you will not have any leaking. These have been on for awhile now and I have not lost any air pressure through them. The 100 Psi model cuts off the air flow from the non leaking tire at almost exactly 90 Psi. This works great with the TPMS also installed on the motorhome with its alarm set at 92 Psi.

Best purchase ever keeps tire presure at point

We installed this in combination with a TPMS system that alerts the driver in the cab if tire pressure is outside of normal parameters. Within a week, one of our drivers ran over a large piece of road debris, which punctured the tire. The alert went off immediately. The crossfire separated the two tires and saved the pressure in the good tire so he could limp it to get fixed.

The color indicator will move as the spinning wheels apply pressure outward. The hose connectors for the valves are not the best. The braided line is awesome,

I saw one of these on a friend's motorhome and decided they would be a good safety factor for my motorhome. You only have to fill one easy-to-get-at valve stem and both tires of your dualie set filled to the same pressure. It warns you when your pressure drops more than 10%. And, if one tire has a fast leak or blow out, a safety valve shuts off the air from the good tire so it doesn't go flat, too. The only problem is, you'd expect the kit to come with two sets, since every vehicle with dualies has two sets of dualies. Much to my surprise, there was only one in the package, now I have to order another one. The drawback is the price and the labor to install, which will require a truck tire-shop.

Less pain to add / remove air, fast control of pressure

Edit review: Bad Bad Bad. One reading gone sideways. In the window the bar turned sideways. The vendor or the manufacture both want you to pay to send it in. If I had broke it I would just order a new one. but it is DEFECTIVE and they can't be bothered to send me a shipping label.Bad business.Saves you time and money. There was a small hickup when we installed this set for our drives.I called customer representative and they were absolutely great and very accommodating. I was going to return the ones we purchased and they were totally great about itAs it turned out, we installed them on a very cold day, the cold made them stick a bit. it took about an hour or two, they started reading correctly and have been right on ever since.it has been about a year now and we love them
