A cap for a valve stem includes a housing extending along an axis from a first end to a second end. A bore extends along the axis from the first end toward the second end and a cup-shaped wall extends circumferentially about the bore for receiving the valve stem. A threaded surface is disposed in the bore for threadedly engaging the valve stem. A flange extends from the first end transversely to the axis and circumferentially around the bore for abutting the rim of the wheel to stabilize the housing relative to the rim of the wheel. Ribs are radially spaced about the housing and extend outwardly from the wall of the housing to the flange reinforcing the housing relative to the flange. |
