Abstract
A tire includes a circumferential tread, a pair of sidewalls, and a pair of bead portions. Each bead portion includes a bead and a bead filler. The tire further includes at least one body ply extending from bead portion to bead portion. The body ply includes a pair of turn up portions radially outside of a respective bead portion. An electronic device is embedded in the tire. The electronic device is encapsulated in a curable adhesive including at least one of natural rubber, styrene butadiene rubber, and butadiene rubber.
Claims20
A tire comprising:
- an inner liner;
- a circumferential tread;
- a pair of sidewalls, each sidewall including an outer rubber layer;
- a pair of bead portions, each bead portion including a bead and a bead filler having an apex;
- at least one body ply extending from bead to bead,
- wherein at least a portion of the body ply is disposed between the inner liner and the outer rubber layer of each sidewall;
- wherein the body ply includes a pair of turn up portions, each turn up portion having a turn up end axially outside of a respective bead and radially below the apex of a respective bead filler;
- an electronic device disposed between the inner liner and the outer rubber layer of one of the pair of sidewalls, the electronic device having an adhesive disposed thereon, wherein the adhesive is one of a solvent-based adhesive and a water-based adhesive, and wherein the adhesive includes at least one of natural rubber, styrene butadiene rubber, and butadiene rubber.
A tire comprising:
- a circumferential tread;
- a pair of sidewalls;
- a pair of bead portions, wherein each bead portion includes a bead and a bead filler;
- at least one body ply extending from bead portion to bead portion, the body ply including a pair of turn up portions radially outside of a respective bead portion;
