Tires, pressure, and the cab.

Dual tires that do not match When one tire in a dual set sits lower than its mate, the truck stops driving balanced. Why that matters for safety, security, and value. Single wheels on a working truck The Greenbox film covers dual wheels and single wheels. A single tire still has to hold pressure, and the driver still needs to see it from the cab. What the cab display is for The Greenbox display in the cab stores the date and time of a low-pressure, high-pressure, or temperature problem. That is the security side of the sale. A pre-trip that follows the truck A yard pre-trip ends when the truck leaves. The Greenbox handheld has a Pre-trip control, and the cab keeps watching after the gate. Steer axle tires and the repeater The film places the repeater inside the steering-axle wheel. Steer tires are singles, and they still belong on a system built for duals and singles. Drive axle duals Drive axle duals put power through two tires that have to share the load. Equal pressure is how that pair stays balanced. Trailer tires after the drop Trailer installation is very similar to the truck. Positions 1 through 4 still need pressure maintained, or the combination does not drive balanced. Temperature on a long grade The cab display stores the date and time of a temperature problem, along with low and high pressure. Heat is part of the watch, not a separate product. Low pressure after you roll Low pressure is one of the events the cab display stores with a date and time. A yard gauge cannot see a leak that starts after dispatch. High pressure on a hot afternoon High pressure is monitored with low pressure. The cab display stores the date and time, which matters when afternoon heat raises a cold-set tire. The sensor bar on the hub bolts The film mounts the sensor bar on the existing hub bolts with a socket. No new bolt pattern is described. About five minutes a sensor. Curved fitting and straight fitting On a dual, one hose uses a curved fitting and the other a straight fitting, each on a valve stem. That is how the film connects the pair. About forty minutes for the truck The film says about five minutes a sensor and about forty minutes for the truck. Trailer installation is very similar. That is the value side of the fit. Where the repeater sits The film places the repeater inside the steering-axle wheel, in the hand hole. That is part of getting wheel readings to the cab. The date and time of a tire problem The cabin display stores when a low-pressure, high-pressure, or temperature problem happened. That record is the security in the sales pitch. Driver handoff and tire notes When a truck changes drivers, tire notes usually change with them. A cab display that stores the date and time keeps the handoff honest. Heat in a dual set A dual that is not equalized makes one tire carry more and run hotter. The film watches temperature and equalizes pressure between the two tires. Trailer positions 1 through 4 The handheld is marked for trailer positions 1 through 4. A trailer without those positions named in the cab is still an unwatched trailer. Every trailer needs the same case The sales case is safety, security, and value for every trailer, not only the tractor that pulls it. Summer pavement and tire pressure Hot pavement raises tire pressure and heat. High pressure and temperature are both events the cab display can store with a date and time. A gauge only works while parked A tire gauge is the right tool in the yard and the wrong tool at highway speed. The cab display is how the film keeps watching after you roll. What shops should plan for A shop can plan the Greenbox fit from the film: socket, existing hub bolts, two fitting shapes, a repeater in the steer wheel, and a receiver in the cab. Truck positions 1 through 6 The handheld marks truck positions 1 through 6. Naming the wheel is how a pressure event becomes a repair instead of a guess. Every truck needs the same case Safety, security, and value are the case for every truck, whether it runs duals, singles, or both. Cold mornings and tire pressure Cold air drops tire pressure before the truck heats up. Low pressure is one of the events the cab display stores with a date and time. Night miles and tire pressure At night a driver cannot walk the tires. The cab display is where low pressure, high pressure, and temperature stay visible. Chrome cover or a visible sensor The film leaves the sensor visible or covers it with a chrome hub cap. The choice is yours. The bolts, hoses, and cab display stay the same. Learn the positions before you roll The handheld has a Learn control next to Pre-trip. A sensor on a hub is not a truck position until the cab has learned it. Safety, security, and value The case for the Greenbox is safety, security, and value on every truck and every trailer. Here is what those three words mean in the film. Questions worth asking first Before you ask for a Greenbox quote, know what the film actually shows: dual or single, cab display, truck and trailer, about forty minutes.
