Abstract
A tire having structures used to notify a driver, passenger, or other observer that a tire tread has worn to a predetermined limit is disclosed. Lattice plies, lattices, meshes, and/or films which are disposed within a tire produce an audible signal that indicates a tire tread has worn to a predetermined limit. The lattice plies, lattices, meshes, and/or films may be used a variety of tire applications.

1-15. (canceled)
A tire comprising:
- a first annular bead and a second annular bead;
- a body ply extending between the first annular bead and the second annular bead;
- an annular belt package, including a first annular belt, disposed radially upward of the body ply and extending axially across a portion of the body ply, and a second annular belt, disposed radially upward of the first annular belt and extending axially across a portion of the body ply;
- a circumferential tread, disposed radially above the annular belt package, comprising at least a tread cap and a tread base, both of which extend axially across a portion of the body ply;
- a lattice ply comprising nodes and a connective medium, disposed radially between the annular belt package and the tread cap, and extending axially across a portion of the body ply;
- and
- a first sidewall extending between the first annular bead and a first shoulder, the first shoulder being associated with the circumferential tread, and a second sidewall extending between the second annular bead and a second shoulder, the second shoulder being associated with the circumferential tread.

A lattice for use in a tire, comprising:
- a plurality of cores having a Shore A hardness of between 70 and 100 and a plurality of connecting filaments,
- wherein at least a portion of the connecting filaments connect to at least one core;
- wherein at least a portion of the connecting filaments meet at a plurality of intersections, and

1 more element
A tire comprising:
- at least one annular structure configured to interface with a wheel;
- a circumferential tread disposed in a crown region of the tire;
- and
- a lattice ply that produces audible noise when exposed to a traveling surface,
- wherein the lattice ply extends axially across a portion of the annular structure configured to interface with a wheel, and
- wherein the lattice ply is disposed radially between the annular structure configured to interface with a wheel and the tread cap.
