A clincher, in the context of tires, refers to a tire with flanged beads that fit into the wheel rim. These are also known as wired-on or hook-bead tires.12

Tire Construction

Beads: The tire has steel beads that are retained by the rim.2
Casing: The tire is constructed with a two-ply cotton or nylon casing.2
Wearing Surface: A synthetic rubber surface is vulcanized onto the casing.2
Inner Tube: An inner tube, typically made of butyl rubber, holds the air pressure and features either a Presta or Schrader valve.2

The term "clincher" can also refer to a decisive fact or argument that settles a matter.13
