A tire inflator having an air compressor to inflate a tire to a predetermined pressure threshold. A central OBD module plugged into in a vehicle uses a short-range radio to transmit to the inflator the predetermined pressure threshold fit for a vehicle. An OBD vehicle bus reader can obtain a VIN of an associated vehicle model. A predetermined tire pressure threshold memory contains a predetermined look-up table of tire pressure thresholds for models. A processor uses the VIN to identify the vehicle model in the look-up table to select the one of the predetermined tire pressure thresholds including a spare tire pressure threshold. A short-range radio wirelessly transmits the looked-up tire pressure threshold including a spare tire pressure threshold to each inflator. The tire inflator has an optical moisture sensor on air inlet or air outlet. The air compressor is disabled when moisture is detected.

A valve stem support apparatus for supporting a valve stem while attached to a pump includes a bracket having a bracket top side, a bracket right side and a bracket left side. The bracket top side has a valve aperture extending therethrough. The valve aperture slidingly receives a valve stem of a tire of a bicycle. Each of the bracket left side and the bracket right side has a screw aperture extending therethrough. A receiving distance between the bracket right side and the bracket left side is wider than a rim of the bicycle. A pair of thumb screws is coupled to the bracket. The pair of thumb screws is threadingly engaged with the screw apertures of the bracket left side and the bracket right side to engage the rim of the bicycle and secure the bracket.

A tire valve stem insertion device and a method of using.

A tire valve stem insertion device and a method of using.

Vehicle wheels and methods of use are provided. The vehicle wheel comprises a first region, a second region, and a third region. The first region is generally annular and comprises a first flange, a second flange opposite the first flange, and a continuous wall comprising an inner surface and an outer surface. A first tire bead seat and a second tire bead seat are defined on the outer surface. The second region is configured to mount to a vehicle axle and is offset from the first flange by an offset distance. The third region connects the second region and the third region and extends inwardly towards the longitudinal axis from an attachment location on the first region to the second region. The third region comprises a first thickness and the second region comprises a second thickness. The first thickness is no greater than 75% of the second thickness.

A tubeless tire and a valve for a tubeless bicycle tire having a rim is provided. The valve includes a stem body having a first and second end with a first opening. A rim gasket is coupled to the first end. A cap is coupled to the second end, the cap having a pin passage therethough, the cap having a circumferential concavity on an outer diameter. A valve seat is disposed between the cap and the second end, the valve seat having a second hole that fluidly couples the first opening and the pin passage. A spring is disposed within the first hole. A seal is movably disposed within the first opening and biased against the valve seat by the spring, the seal being movable between a first position and a second position.

A valve stem to be mounted to a valve mounting hole of a tire wheel includes a stem body that is pipe-shaped, contains a valve core inside, and has a proximal end to which an electrical circuit unit is fixed, and a cover member made of elastomer and covering an outer side of the stem body. The valve stem includes an engagement groove formed on an outer circumferential surface of a proximal end of the cover member to engage with an opening edge of the valve mounting hole, and a weight adjustment member having a higher specific gravity than the cover member and made of a material different from that of the stem body. The weight adjustment member is embedded in the cover member and positioned closer to a distal end of the cover member than the engagement groove.
