A method for inflating a tyre mounted on a corresponding wheel rim comprises the following steps in sequence; placing a tool at an operating position, where a first bead of the tyre is interposed between the tool and a second bead of the tyre, and one end of tool is positioned axially between a first flange of the rim and a first rib of the rim and positioned radially between an outside surface of the rim and a tread of the tyre; blowing a gas under pressure through an inflation valve of the tyre into a chamber delimited by the tyre and by the rim, with the tool at the operating position, so that the first sidewall of the tyre is pressed against the end of the tool; removing the tool from the operating position.

The present disclosure provides tire pressurization/sealant systems that can include a coned plunger valve. The present disclosure also provides tire pressurization/sealant systems that can include, for example, a first fluid source, a plunger valve assembly, a first conduit extending from the first fluid source to the plunger valve assembly, and a tire pressurizing hose extending from the plunger valve assembly. The present disclosure also provides methods for providing sealant to a tire via a tire pressurizing hose and cleaning out the tire pressurizing hose. The methods can include providing tire sealant to a tire via a tire pressuring hose through a plunger valve assembly and reconfiguring the plunger valve assembly to provide an aqueous solution through the hose to clean out the valve assembly and the hose.

An apparatus can include a first tube. The apparatus can include a manifold coupled to the first tube. The manifold can have an opening. The apparatus can include a second tube at least partially disposed in the first tube. The second tube can enter the first tube via the opening of the manifold.

A load-based tire inflation system for a heavy-duty vehicle comprises at least one source of fluid pressure, suspension structure of the heavy-duty vehicle, a tire and wheel assembly and a system to control fluid pressure in the tire and wheel assembly. The suspension structure is located between a frame member and an axle and has a condition indicative of a weight of the heavy-duty vehicle. The tire and wheel assembly is operatively mounted to the axle and is in fluid communication with the source of fluid pressure. The control system controls fluid pressure in the tire and wheel assembly in response to the condition of the suspension structure.

A compressor unit (38) for supplying pressurized medium to a tire mounted on a vehicle wheel rim (34), having a compressor (58) for exerting pressure on a fluid medium that is to be conveyed into the tire. The compressor unit (38) is dimensioned to be accommodated in a center bore (44) of the vehicle wheel rim (34) when the vehicle wheel rim (34) is in the mounted state on a wheel hub (62); and the compressor (58) can be driven by a drive unit (56) positioned in the vicinity of the center bore (44) of the vehicle wheel rim (34). The compressor unit (38) is usable with a vehicle wheel rim (34) having a pressurized medium supply device (22) for a tire that is mounted on the vehicle wheel rim (34), as well as a vehicle having a vehicle wheel that includes such a vehicle wheel rim (34).

The present disclosure provides tire repair assemblies that can include: a tire sealant tank; an air assembly coupled to the tire sealant tank; a valve configured to control fluid communication between the tank and the air assembly; and a currency operating assembly configured to control the valve. Methods for repairing tires are also provided with the methods including providing tire sealant to a tire from a tire repair assembly upon depositing currency in the tire repair assembly. A stand alone currency operated tire repair assemblies are also provided with the assemblies including: a tire sealant tank; an air compressor operatively coupled to the tank; a valve operatively aligned between the tank and the air compressor; a flow meter operatively aligned between the tank and the air compressor; and computer processing circuitry operatively coupled to the air compressor, the valve, and the flow meter.

An indirect tire pressure monitoring system is provided that estimates a pressure in a tire more accurately than before. The system includes an estimated internal pressure transmitter (control unit) that calculates and transmits an estimated internal pressure of a tire when a vehicle is travelling based on a wheel speed, a measured internal pressure of the tire at halt and a measured temperature of the tire at halt. The system measures the internal pressure and the temperature for each tire, and carries out deflation evaluation independently for each tire.

Disclosed are a method and a system for monitoring the pressure of a tire. The system measures frequencies of multiple tires mounted on the vehicle, sets a first average frequency for a normal pressure state and a second average frequency for determination of a low pressure state, wherein the first average frequency is calculated by accumulating the measured frequencies for each speed interval in a stop mode and the second average frequency is calculated by accumulating the measured frequencies for each speed interval in a driving mode, calculates low-pressure probabilities for each speed interval of the tire by using the second frequency, a predetermined low-pressure reference frequency, and a predetermined frequency determination interval for determining low-pressure, and determines whether each tire is at low pressure state by aggregating the low-pressure probabilities for each speed interval of the tire.

A tire inflation system is provided comprised of a wheeled body that is comprised of a means to inflate and deflate tires using at least one inflator. The system is also comprised of a plurality of safety measures such as at least one pressure switch, and at least one emergency deflate button. The system is also comprised of at least one muffler to reduce the noise of the system during use. The system may also have at least one hose that can attach to a tire and to an air inlet/outlet of the system to facilitate inflation of the tire.
