  • Wheel assembly
    Patent number: 9884511
    Abstract: A wheel for a pneumatic tire has a rim with one monolithic bead seat and a removable beat seat. The removable bead seat has two halves that embrace the rim and engage a groove to retain the tire. The removable bead seat may have a second lip either monolithically formed or as a part of a separate retainer that bolts to the bead seat. The wheel may be made from aluminum alloy.
