Crossfire dual tire pressure

I have been holding off getting these for the rear duals, but I will be getting new tires in the next couple of weeks so this would be a good time to have them installed. If I also add a TPMS would you just use one sensor on the crossfire rather than one on each tire?

Crossfire Dual Tire Pressure Equalization System, 95 PSI, one per pkg. (CF95STABT) : Amazon.com : Automotive

I've put this on both coaches I've owned. I have yet to trust putting a TPMS system back since my experience with the TST. I just keep a close eye on my tires the conventional way.

I'm happy with the performance of the Crossfire setup

How did you select the crossfire preset pressure range. Example if you run 95 psi on the rears do you go with the 95 psi preset or move up to the 100 psi preset and still run 95psi in the tires. I don't know if that makes sense. Thanks

Yes. One sensor per Crossfire.

I selected my cold pressure recommendation of 85 so when I check them cold I know what I've got in there. They rise throughout a trip and the red flag comes into view. If it doesn't I know there's an issue.

I am curious what bad experience have you had with TST ?

5 out of the 6 transducers corroded onto my valve stems so I had to have them cut off. With that the tires had to come off the rims so that new stems could be put on and then the tires had to be remounted. It cost me $250.00. I still have to have the two on my tow dolly cut off since they are seized on as well.

What happened with your TST TPMS, you mentioned

It still sits in my garage. I wouldn't feel right selling for fear the same thing would happen to whom ever I sold it to. Eventually I'll throw it out. Probably after I have the two sensors cut off of my tow dolly wheels.

I'm not clear on how a TPMS works with the Crossfire system. If a tire blows out an internal valve keeps the remaining tire from losing pressure. If so, how does the TPMS sensor get triggered? I've looked at their website and it doesn't seem to address that.

If one tire blew the cross fire would still allow about 10psi to escape which should trigger your tpms system. The other method is to install either flow through sensors on both valve stems or use a tpms with internally mounted sensors

We're running 105 CF's, with single tire monitor. I have/had two concerns, but felt the upside of CF's were enough to offset them.

1) Yep, what happens if one of the tires has a slow leak, or rapid failure. And yes, depending on the CF's to not shut off until enough PSI is lost to trigger the tire sensor.

2) My biggest concern, is the problem that Park House Tires had installing the CV's on my wheels. They got them on, with some 'tweaking'. The Manager suggested if we ever needed to have a tire repaired on the side of the road, to be sure the tire guy coming knew that we had CF's before he came. (I kept the existing extender hose from inside wheel to outside wheel, as good chance the roadside gent will not want or have the proper equipment to re-hook the CF's back up. Will probably need to do either the extender, or just air the inside tire to the proper inflation and install it. I'll then go into a tire shop that has the time and the gear needed to re-install the CF's.)

Best to all,
Smitty
