A bicycle rim has rim a pair of rim flanges that defines a tire channel. A rim strip extends across the tire channel. The rim strip includes a pair of flange bumpers configured to cover the rim flanges. The flange bumpers each define a flange channel in which one of the rim flanges is received. A pair of safety humps define corresponding tire seating sections where a tire is seated when inflated. The rim strip further includes a drop seal that seals with the beads of the tire to facilitate seating of the tire during inflation.

An inflating device includes a bottle for containing a pressurized air, a housing is secured to the bottle and includes an orifice communicating with an inner chamber of the bottle, a valve piece is engaged in the housing and includes a shank engaged in the orifice of the housing, and a spring biasing member is engaged with the valve piece for biasing the valve piece to engage with the housing and to make an air tight seal between the housing and the valve piece. The pressurized air and a fluid contained in the bottle are allowed to flow out through the orifice of the housing when the pressurized air includes a pressure greater than a spring biasing force of the spring biasing member.

A self-retracting air compressor assembly includes a motorized pump device that drives in opposing directions. A reservoir tank is in fluid communication with the pump device and stores air pumped by the pump device. The air compressor includes a cord assembly that supplies air and electrical power from the pump device. The air compressor assembly pumps air when the motor is driving in a pumping direction, and self-retracts the cord assembly when the motor is driving in a winding direction.

A dual-air tap inflation nozzle includes a body, a first cap assembly, a second cap assembly, a slidable valve slidably disposed in the body, and a lever member. The body has a first end, a second end, a first passage and a second passage in communication to the first passage. The first cap assembly is mounted to the first end and has a third diameter. The second cap assembly is mounted to the second end and has a fourth diameter larger than the third diameter. The lever member is abutable against the slidable valve to cause the second passage moved in relation to the first passage. Thus, the second passage is in communication with a first inflatable space or a second inflatable space of the body.

An inflation manifold connected to dual pneumatic tires by air hoses provides a central location for tire inflation and location of pressure sensors. A hose block connected to dual pneumatic tires by air hoses provides a central location for location of pressure sensors. The pressure sensors may be TPMS sensors or a combination of TPMS sensor and pressure gauge.

An air chuck with variable angle swivel head, having a head, a handle having a front face having a manufactured angle, and a swivel mechanism, which includes a banjo bolt, an air chuck tip and a pin, which together provide an air passage, whereby the head is connected to the handle by the swivel mechanism, and the manufactured angle of the front face of the handle lies in the range of 15 degrees to 45 degrees.

In a device for discharging tire sealing agent from a container which can be connected to a pressure source and to a tire valve, a check valve is provided in the connection to the pressure source and/or in the connection to the tire valve.

A tire pressure maintenance device is shown and described. The tire pressure maintenance device may include a sensor mechanism configured to detect at least one predetermined condition of a vehicle. The tire pressure maintenance device may also include a control mechanism operatively coupled with the sensor mechanism, the control mechanism applying a predetermined pressure to a tire of the vehicle in response to the predetermined condition.
