its fairly inexpensive, i can see it paying for itself in lost down time and less road side service calls. let alone longer tire life. i think the cost benefit is more with super singles than with duals because with super singles you cant limp it anywhere with duals you can drag your air hose out drive a little ways stop air up again and drive till you get somewhere you can get it fixed not very practical with super singles as there is not another tire to carry the weight when the other tire is low. i cant see not running it for the price in my situation. especially because i am puncture prone.
just think of the down time you have had in the last year (lost revenue) waiting for tire repairs, if you can get your tires fixed at your convenience vrs when it happens figure how much more up time you would have in your operation. let alone if you get stuck on the side of the road somewhere and have to wait for a service truck, then you have service call cost as well as down time. i think for me it would pay for itself within a few months. if my experience with this system goes as good as some friends of mine has ill retrofit every trailer i buy with this system.
here is my truck and the trailer im getting this system retrofitted on

Cheap insurance,whether it's SS or duals. For quite a few years i haven't had a road call for trailer tires,except when the driver runs over something big. Pick up a trailer with a flat and 10-15 minutes it's able to drive to a tire shop. Some day they will get a system for the tractor's.

Trouble is.... it's prone to giving false positives. It can come on when nothing is wrong, and then you take it to the shop and they try to fix what's wrong and the light just.... won't go off. Half the trailers I pick up have that light taped over with duct tap or electrical tape.
Last thing you want when you're rolling through a scale is a "something's wrong" light shining for the DOT guys to see. -
good thread. i am in the process of ordering a new trailer. i spec'd it out with air inflation system. Their first choice was meritor. i am also looking into Tiremaxx, as this trailer will have Hendrickson's Intraxx axles. Pretty certain I will have wide based tires on it also. Looking into air disc's also. If i do that it will be all done thru Hendrickson.

well just a update the system is done being installed, everything seems to be working how it should. the shop did a nice clean installation on everything. they also fixed a light replaced my trailer light plug as it was in bad shape and repaired some questionable wiring that was on my to do list, replaced a quick release valve on one of my dump cylinders that was leaking and the total damage came out to $1422
Oxbow Thanks this. -
Whatever system you choose, figure out some kind of T fitting arrangement so you can confirm the actual pressure in the tires from time to time. We haul all sorts of high dollar trailers that have had these central inflation systems installed, and have also had several failures, no lights going on or any warning. It is similar to the automatic greasing systems that have been around for years. Seems like a no brainer, but the systems are not trouble free nor fool proof.

Does the type of spindle you have on your axle matter? I had some work done to my trailer and the mechanics told me I had one spindle different than the others. I must have been repaired in the past, before I bought the trailer. The three original spindles have a hole through the center and the one is solid.

there is a place at each wheel to verify air pressure. also one at the control box.
there is a difference in the kit if you have tapered or straight hubs (large or small outer caps you can tell)
the center plugs get removed and replaced with ones from the kit. they come out by drilling a hole in them and using a slide hammer. new ends get pressed in.
the guy that installed my system supplied me with all the literature including installation instructions. it really looks pretty straight forward to install. two holes are drilled and tapped in the center of the axle and vent lines are installed here encase of a air line failure inside of the axle then two holes are drilled closer to the ends of the axle tubes axle air supply lines are run in threw these. end plugs are removed and replaced with the ones from the kit outer axle hub seals are replaced air line attaches from the replacement outer hub to the tire, air lines from the Axel to the control box. air line from your air tank to the control box. constant power wire to the control box and warning light installed. -
