Tire Pressure

That's the drawback of the system. My trailer actually tells me if I have a low tire, but otherwise I just glare at them when I pre/post trip.

 

I driver reefer so on our trailer we get a a little white indicator light that illuminates on the trailer and can be seen on my driver's side mirror while I'm driving. This let's me know there is something wrong. Not sure how it's setup for you on the flatbed but yeah you can't check those tires with a standard gauge it's a self inflating system.

You should see a warning somewhere on your truck or trailer. A different color light on your trailer or maybe an indicator on your dash. I just don't know where it would be on your trailer. I think you said you pull flatbeds? Look somewhere on the left side of your trailer for a little light (different from the amber ABS light) maybe check the front of the trailer. It should definitely be somewhere you could see it from your driver's side mirror or maybe inside your truck on the dashboard somewhere.

 

That's the benefit of being a door swinger, of course the downside is our load can go from fine to fiber while we sleep.

 

True but dispatch is usually calling you panicking

 

Hmmmm don't see anything. What about the entire left side of your trailer? Can we see a pic of that and maybe a pic of your dash board. Curious if you have a TPM monitor on your dash somewhere.
