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.

First claim

What is claimed is:

1 . 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.

2 . The tire of claim 1 , wherein the adhesive is a non-pressure sensitive adhesive.

3 . The tire of claim 1 , wherein the adhesive is a solvent-based adhesive including filler and curative dissolved in a volatile organic liquid.

4 . The tire of claim 1 , wherein the adhesive is a water-based adhesive including filler and curative suspended in an aqueous media.

5 . The tire of claim 1 , wherein the adhesive is a non-imide-based adhesive.

6 . The tire of claim 1 , further comprising a pair of chafers, each chafer at least partially wrapping around one of the pair of bead portions.

7 . The tire of claim 1 , further comprising a pair of abrasion portions, each abrasion portion at least partially wrapping around one of the pair of bead portions.

8 . 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; and at least one electronic device embedded in the tire, wherein the at least one electronic device is encapsulated in a curable adhesive including at least one of natural rubber, styrene butadiene rubber, and butadiene rubber.

9 . The tire of claim 8 , wherein the at least one electronic device is a radio frequency identification tag.

10 . The tire of claim 8 , further comprising a pair of wire reinforcements, each wire reinforcement wrapping around one of the pair of bead portions.

11 . The tire of claim 8 , wherein the at least one electronic device includes at least a first electronic device and a second electronic device.

12 . The tire of claim 8 , wherein the curable adhesive is a solvent-based adhesive.

13 . The tire of claim 8 , wherein the curable adhesive is a water-based adhesive.

14 . A method of embedding an electronic device in a tire, the method comprising:
forming a tire carcass by:
providing a pair of bead portions, each bead portion including a bead and a bead filler,
providing a body ply, and
wrapping a portion of the body ply around each of the pair of bead
portions; providing an electronic device; encapsulating the electronic device with an adhesive selected from the group consisting of a solvent-based adhesive and a water-based adhesive, wherein the adhesive includes at least one of natural rubber, styrene butadiene rubber, and butadiene rubber; affixing the electronic device to the tire carcass; forming a green tire by providing sidewall compound and a tread compound on the tire carcass; and curing the green tire.

15 . The method of claim 14 , wherein the affixing the electronic device to the tire carcass include affixing the electronic device to the body ply.

16 . The method of claim 14 , wherein the affixing the electronic device to the tire carcass include affixing the electronic device to one of the pair of bead portions.

17 . The method of claim 14 , wherein the forming a tire carcass includes providing an inner liner.

18 . The method of claim 17 , wherein the affixing the electronic device to the tire carcass include affixing the electronic device to the inner liner.

19 . The method of claim 14 , wherein the adhesive is a non-acrylic adhesive.

20 . The method of claim 14 , wherein the curing the green tire causes the adhesive to crosslink with the tire carcass.
