TPMS on trailer with PSI inflation system?

Just bought a new trailer with wide singles and PSI inflation system. Have singles on my truck also. Looking to purchase a tire pressure monitoring system. Wondering if anybody has any experience with putting a tpms on a trailer with an inflation system. Im not looking to break the tires down to put a sensor on the inside. The trailer has a warning light that supposed to light up if a tire is deflating. Maybe i will be better off just putting the tpms on the truck. Any thoughts? Thanks

Answer this question I have this problem too

Is this a good question?

Picked up a trailer with a FLAT tire. The auto inflate filled it saved a road call. Made it to the shop no problem.

I have a truck system technology system. It is available with flow through sensors.

You shouldn't need monitoring if you have auto inflation. When the white light comes on, that means air is going into one or more of your tires. If the light stays on for an extended period of time you should visually inspect your tires to find out why.

I once picked up a trailer that had been sitting for about 6-8 months, it had auto-inflate, the white light stayed on or about an hour as all the tires were low on air from sitting for so long.

the tpms system will give you a read of the pressure going into the tire, with a psi system, but not of the actual tire pressure unless you install a sensor inside the wheel (not connected to the valve).

A single TPMS sensor placed between the regulator and the axle would give a read on overall system pressure. If the system pressure is at 120psi then the tires would also be at 120psi.

The one way check valve located in the line going from the axle to the valve stem is there to prevent back-flow, so there is no way to actually measure each tire pressure without removing each line.

not really. since tire pressure rises with temperature the sensor would always show 120 psi - even if the tire was at 140psi. it would also not alert about a leak or the tire air temp.
