Abstract
A composite wheel is used with a pneumatic tire having at least one bead. The composite wheel includes a circular drum having an elongated skirt extending out from the circular drum substantial perpendicular thereto along the periphery of the circular drum. A tire bead retention member receives the bead of the pneumatic tire and is then removably secured to the elongated skirt with a nut and bolt fastening system. The removability of the tire bead retention member enables the pneumatic tire to be dismountable from the composite wheel. Run flat devices are attachable to or formed with the tire bead retention members prior to mounting the drum body which allow the pneumatic tire to run without air without destroying sidewalls of the pneumatic tire.
Claims5
A composite wheel for a pneumatic tire having at least one bead and a side wall extending out therefrom comprising:
- a drum defining a longitudinal axis, said drum including a circular drum body extending perpendicularly to said longitudinal access and an elongated skirt extending out from said drum body defining a circular cross section;
- and
- a tire bead retention member receiving the bead of the pneumatic tire such that said tire bead retention member positions the bead of the pneumatic tire outside said circular cross-section and provides the sole restraint of the bead against axial and radial separation from said composite wheel, said tire bead retention member being removably securable to said elongated skirt, said tire bead retention member including a run flat device extending out therefrom to an external edge defining an outer diameter and having a side wall separator disposed adjacent said external edge whereby said side wall separator preventing the side wall of the pneumatic tire from folding onto itself.
