Best TPMS system for tractor?

I have tested many of them and they are not accurate.

 

my gauge is 4 off. so 105 is 101 on my gauge. seems to work good when checking tires.

 

Crossfire air equlizers used to be big in the past.

 

The company from the Atlanta area TPS I think their called, I’m not in the truck at the moment. It’s just sensors and a LED in the cab, I don’t even use the repeater any more and it’ll still pickup the tires back on the spread axle/s.

2 years or so now. Nice, nice, nice addition to have I must say.

 

The fleet I ran with used Doran. It was accurate and cheap$.

Saved me alot of time when I ran over a bolt on a wide-single and knew it was loosing pressure. Was able to pull over and plug it, in a safe spot rather than knowing something was wrong when I felt the tire blow or shred apart.

you can check the pressure of every tire on the truck in less than 10 seconds... Yeah, have fun with your manual pressure gauge, you can't do it while driving down the road...

 

Boooo

All new trucks must have something like this Doran factory installed...

 

TSTtruck.com is what it is.

...about $50 a sensor plus the screen. Think they have bundle packs that will shave some of the coat off.

 

FYI, piston-plunger gauges typically only meet their accuracy (closeness to known value) near the middle of their range, with the same temperature air pressure etc...

It may be 4 lbs of error of on a 72 degree day but not when it is freezing or in the middle of the desert with a stick gauge.

What they do have is precision...at least with repeated measurements on the same tire.

Accuracy = distance from known value
Precision = repeatability of values in same conditions.​

The big problem with those pencil types if if you are running say 17.5s with air valve extenders. Even if they both tires read the same pressure the inside tire could be seriously overinflated if the air valve extender restricted flow causing a lower reading.

Digital and dial gauges which don't depend on that initial acceleration like the stick versions are about the same price but much more accurate, especially when comparing multiple tires.
