Cat eye pressure monitors. Good or bad?

Cross fire kept the tire inflated when it had a hole the size of a golf ball? You can add me to the list of confused.

 

OK so here's a question: If I blowout one of my duals with one of those cats eye things will it drain all the air from the good dual because it's trying to equalize?

 

That was my first thought as well. I mean ####, at least try and make it a little believable.

 

No they quit equalizing at approx. 20lbs low, like mine are rated at 100 so the eye opens at 90 and quits equalizing at 80psi.

 

No, it's the Crossfire system. I'm not sure about the new trailers. I run cryogenics and this particular trailer is about 20 years old. The Crossfire was an add-on. I'm not sure the particulars of the system because I've never paid too much attention. Like another poster had said, they equalize the pressure in the tires or in this case, (super single), it inflated it to the set PSI. Hope this helps, maybe I'm the confused one?

 

Believe what you want, it makes no difference to me.

 

Tire Pressure Monitoring systems that alert in cab are a joke, just like the TPMS systems on cars. I bought an aftermarket kit for my pickup back in '01, scrapped it in '05. Constantly inaccurate, I could inflate a tire, when cold, to 20 psi above the setting on the monitor and within a two days it would read low, put a gauge to it and the pressure was still the same. That and the sensors loved to breakoff inside the tire, they would continue to read the pressure and send it to the display, but the whole time they were tumbling around inside the tire. Even the factory systems are a joke, I know guys with brand new Audi's who are having to check their air pressure everyday because the TPMS tells them it's low. The Discount Tire store by me, 80% of the their "free air" customers are people with TPMS systems, even the store managers wife's Lexus, she has to bring it in every 3 days for an air check because the TPMS tells her something is low, but when gauged it's fine or above. This was the answer to a problem that didn't exist, caused by people not paying attention.

 

I'm sorry, but there is nothing out there that is keeping a tire with a golf ball sized hole in the sidewall inflated.

It's always off in my Buick. Seems to think the spare is always flat. I do have to say the TPMS on my Tundra is spot on though.

I know the in cab TPMS we had at my old company never worked. The inflation systems they used in conjunction with the reporting system in some trailers did work very well even though it wouldn't report like it should. Where I work now, the auto inflation systems were so poor that they just ripped them out. I don't think they had a monitoring system, just inflation. They were test units that we didn't pay for though. We get a lot of companies coming in wanting to test stuff.
