Anyone know what PSI these units are looking for?

I've got all tires at 35psi per the manual and the spare at 50psi.. Still getting "low tire." I'm about "this far" from finding a fuse and pulling it in this system..

Anyone have any suggestions?

Thanks

Jeff

 

Old topic.... your missing this answer. Fill your tires to 37 or 38PSI exactly the same in all four, cold. The spare doesn't matter, the H3 can only monitor 4 tires.

What it is looking for is a difference in PSI from any one tire. If any monitored tire is out 3-5%, you get the warning.

The spare has to be programmed in, in the place of one of the four on the ground to be monitored. If you do not know which for are being monitored (you bought used), make sure your spare is exactly the same PSI as the rest and your problem is over.

BTW, there is no fuse to pull, the default is warning.
