BACKGROUND OF THE INVENTION
[0002] 1. Technical Field
[0003] The present invention generally relates to pneumatic tires
and, more particularly, to a pneumatic tire in combination with a
tire tag. Specifically, the present invention is related to how the
tire tag is mounted to the pneumatic tire and the location of the
mounting.
[0004] 2. Background Information
[0005] Various types of tire tags in the nature of tire monitoring
devices and tire identification devices are known in the art. Tire
monitoring devices may be configured to read temperature or
pressure and store the information for later retrieval. These
devices may also be configured to transmit the information from the
tire to an outside reader. Tire monitoring devices may use the
information to trigger an alarm when the temperature or pressure of
the tire reaches a limit. Tire identification devices allow a tire
to be identified through its manufacturing process and after the
tire is placed into service. Tire monitoring and identification
devices may be passive or active depending on design and desired
functions.
[0006] One type of tire identification device known in the art is a
tire identification chip (tire ID chip). A tire ID chip stores a
unique identification number that may be read by an interrogation
signal sent by a device that obtains the information from the tire
ID chip. Tire manufacturers wish to mount one tire ID chip into
each tire manufactured so that the tire may be tracked during the
manufacturing process and during use on vehicles.
[0007] Given the wide variety of monitoring and identification
devices, a wide variety of mounting configurations also exist for
these devices. Exemplary known mounting configurations include
building the monitoring device into a tire sidewall, building the
monitoring device into the bead filler, attaching the device with a
patch to the tire sidewall, attaching the device directly to the
innerliner with an adhesive, connecting the device to the rim that
supports the tire, and mounting the device to the valve stem of the
wheel.
BRIEF SUMMARY OF THE INVENTION
[0008] The invention provides a first configuration that mounts the
tire identification or tire monitoring device in one of the belts
of reinforcing cords positioned in the crown of the tire. The
identification or monitoring device may take the place of one of
the reinforcing cords, may be positioned between reinforcing cords,
or may be positioned at the splice that is used to form a loop out
of the reinforcing cord ply.
[0009] The invention also provides an embodiment wherein the tire
identification or tire monitoring device is mounted in a depression
formed in the outer surface of the sidewall. The tire
identification or tire monitoring device may be encapsulated with
an encapsulation material in the depression.

first mounting configuration for the tire monitoring or tire
identification device.

DETAILED DESCRIPTION OF THE INVENTION
[0019] A first embodiment of a tire and tire tag combination is
indicated generally by the numeral 100 in FIGS. 1-3. Combination
100 generally includes a tire 102 and a tag 104 that is mounted to
tire 102. Tag 104 may be an identification device or a monitoring
device. In the embodiment of tag 104 shown in the drawings, tag 104
has a central body 106 with wires 108 extending from opposed sides
of body 106. Body 106 may include any of a variety of elements that
are used to store and present information about tire 102 to a
reader (not shown) that requests the information.
[0020] In the first mounting configuration, tag 104 is built into
one of the reinforcing belts 110 disposed in the crown of tire 102.
Each reinforcing belt 110 includes a plurality of reinforcing cords
112 disposed adjacent each other. Each reinforcing cord 112 is
encased in a rubber material 114 or other suitable materials. Each
belt 110 is wrapped circumferentially around tire 102 with the ends
of belt 110 being joined at a splice 116. Splice 116 is generally
parallel to wires 112. In the first mounting configuration, tag 104
is located at splice 116 in order to create a built-in mounting
location for tag 104. Tag 104 may be embedded in the adhesive of
splice 116. Tag 104 may be built into the outermost belt 110 in
order to improve readability and to decrease its exposure to the
curing heat used to attach belt 110 to the body of tire 102. The
location also protects tag 104 from tire bending forces during tire
shaping.
[0021] Tag 104 may be built into splice 116 when splice 116 is
formed. In the alternative, tag 104 may be prebuilt into ply 110 at
splice 116 or at another suitable location. For instance, in
another embodiment of the invention, tag 104 replaces one of
reinforcing cords 112 as shown in FIG. 3A. In FIG. 3B, tag 104 is
positioned between adjacent reinforcing cords 112. These locations
have the benefit of protecting tag 104 from curing heat, protecting
tag 104 during tire shaping, and placing tire tag 104 in a location
where there is less interference with other tire structures. This
location also places tag 104 in a location where it does not
protrude from an internal or external surface of tire 102. The
location also does not rely on adhesive for durability of the
connection between tag 104 and tire 102. Adjacent belts may use
suitable mechanisms in opposed locations to tag 104 for tire
uniformity.
[0022] The second embodiment of the tire and tag combination is
indicated generally by the numeral 200 in FIGS. 4-5. Combination
200 generally includes a pneumatic tire 202 and a tag 204 that is
mounted to one of the sidewalls 206 of tire 202. Tag 204 is mounted
to sidewall 206 in a location that is adapted to be above the rim
208 when tire 202 is mounted to rim 208. In one embodiment, tag 204
may be mounted immediately above rim 208 where the sidewall is
thicker and flexes less. This area is identified by numeral 209 in
FIG. 4.
[0023] Tag 204 is disposed in a cavity 210 defined by sidewall 206.
Cavity 210 has sufficient dimensions to receive the entire body of
tag 204 with additional room for an encapsulation material 212. In
this specification, encapsulation material 212 may be any of a wide
variety of materials that will adhere to tire 202 in order to help
secure tag 204 to tire sidewall 206. A variety of known adhesives
or repair compounds/materials may be used as encapsulation material
212. Encapsulation material 212 may be a rigid material or a
relatively flexible material. One exemplary rigid encapsulation
material is an epoxy that prevents the elements of tag 204 from
flexing with respect to each other during tire use.
[0024] This embodiment allows tag 204 to be installed after tire
202 is fabricated and cured. The embodiment also allows tag 204 to
be selectively placed in tire 202. This mounting position does not
expose tag 204 to curing heat and prevents tag 204 from extending
above the profile of sidewall 206. The embodiment also allows for
removal and replacement of tag 204 depending on the type of
encapsulation material 212 used.
[0025] In the foregoing description, certain terms have been used
for brevity, clearness, and understanding. No unnecessary
limitations are to be implied therefrom beyond the requirement of
the prior art because such terms are used for descriptive purposes
and are intended to be broadly construed.
[0026] Moreover, the description and illustration of the invention
is an example and the invention is not limited to the exact details
shown or described.
