Where the repeater sits
Hardware on the hub does not help a driver who cannot hear it. The film places a repeater inside the steering-axle wheel, in the hand hole. That is a plain location. It is not “mount the box somewhere near the battery” and it is not left to the installer’s taste. The steer wheel is a single-tire position, and it is also the home of the repeater that supports the rest of the truck.
The path the film shows runs from the sensor bar on the hub, through that repeater, to a receiver the driver can see in the cab. Antennas and a power lead are in the kit because a wireless reading still needs a way to arrive. If the repeater is skipped, or tossed in a bin until “phase two,” the bars on the duals are not the system the film finished. They are parts. The cabin display cannot store the date and time of a low-pressure, high-pressure, or temperature problem for a signal that never gets to the cab.
Safety depends on that path being complete on duals and singles. On a dual, the wireless transmitter equalizes pressure between the two tires and monitors low and high pressure. The driver only gets the benefit of that monitoring when the cab actually shows it. A truck can be mechanically equalized at the wheel and still be unmanaged if nobody sees a problem start. The truck drives balanced when pressure is maintained. It stays managed when the repeater and the receiver are in the places the film uses.
Security is the receiver location as much as the repeater location. The film says to put the monitor where it is convenient for the driver to see. A repeater buried correctly and a handheld buried in a door pocket is only half the instruction. Power and mute are on the device so it can live in the cab without becoming a nuisance the driver defeats. Pre-trip and Learn, and positions 1 through 6 and 1 through 4, only matter if the driver can reach them.
Value is not having a second wiring project invented on the spot. The film’s about forty minutes for the truck includes this placement, and about five minutes is the figure for a sensor. Trailer installation is very similar, but the repeater the film points to is inside the steering-axle wheel of the truck. Plan the steer wheel when you plan the duals. The optional chrome hub cover is a separate choice for the sensor, not a cover for the repeater.
The website’s lines about an all-in-one package and built in the USA are site claims. The film shows the repeater, the hand hole, and the cab. A screen that reads 104 PSI and 53°F is one moment after the signal has a place to land. It is not a specification.
Every truck and every trailer needs the full path for safety, security, and value. When you inquire, say whether the tractors are the first fit or the trailers are. Someone replies about your trucks. If the form does not go through, email customersupport@truckstpms.com with the note the page kept for you.
Open the steer-wheel hand hole before you sell the job as simple. Some wheels are clean. Some are full. The repeater has to sit in there without resting on a sharp edge or blocking the hole so badly that the next tire change becomes a fight. Tie the lead so it cannot fall into the rotating assembly. If you are not sure the lead is clear, do not guess with the truck on the ground and the driver already in the seat. Power the receiver and confirm a position reports before you release the truck. A repeater that is "in there somewhere" and a cab that stays blank is an unfinished install, even if every hub bar looks right in a photo. The hand hole is a service point. Note it on the tire chart so a wheel-off brake job puts the repeater back in the same place.
