Abstract
A pneumatic tire includes a body, a belt package, and a tread package. The tire includes a layer of rubber disposed between the body and the tread package. The layer of rubber creates a thickness of between about 0.5 millimeters and about 1.5 millimeters between the cords in the body and the cords in the belt package. The layer of rubber is fabricated from a rubber having a stiffness greater than the rubber in the body of the tire. This configuration provides a tire having improved cornering coefficient, reduced vibrational levels, and less coarse road noise with only a small increase in rolling loss.
Description
- This application is a continuation of U.S. application Ser. No. 09/559,705 filed Apr. 27, 2000; the disclosures of which are incorporated herein by reference.
- 1. Technical Field
- This invention generally relates to pneumatic tires and, more particularly, to a pneumatic tire having an extra layer of rubber that improves tire performance. Specifically, the present invention is directed to a pneumatic tire having an increased rubber gage between the tire body and the belt package to improve the performance of the tire.
- 2. Background Information
- A pneumatic tire used on a typical automobile or truck includes a basic tire carcass member that may have reinforcing cords radially disposed in its body. These reinforcing cords typically radiate out from the center of rotation of the tire. A reinforcing belt package may be positioned on the outer surface of the carcass. The reinforcing belt package may include a layer or layers of reinforcing cords that give the tire strength and durability. Tires also include a tread package having the tire tread that is positioned outside the reinforcing belt package.
- In recent times, automobile manufacturers desire tires that are tuned for a specific automobile model. This requirement has developed in part because current suspensions are sensitive enough that tires can make noticeable changes in the ride and handling of an automobile.
- Tire manufacturers tune tires by varying the materials that are used in the tire and by varying the configuration of the elements within a tire. Various tire configurations are known for improving characteristics such as road noise, ride, rolling resistance, strength, vibration, and cornering force. Although various tires are known in the art having configurations directed to one or more of these characteristics, a tire is desired that has an improved cornering coefficient, reduced tire vibration levels, reduced coarse road noise with only a small increase in rolling resistance.
- In view of the foregoing, the present invention provides a pneumatic tire configuration having increased rubber gage between the body ply and the belt package. The rubber gage is sized to improve the cornering coefficient of the tire while reducing vibrational levels. The increased gage also improves the coarse road noise of the tire. These advantages are achieved without an undesirable increase in rolling loss.
- The invention provides a pneumatic tire, including a body having at least one layer of body cord; a belt package having at least one layer of reinforcing cord; a tread package connected to the belt package; and a gage of rubber disposed between the belt package and the body; the gage of rubber spacing the body cord from the reinforcing cord a distance in the range of 0.5 millimeters to 1.5 millimeters.
- The invention also provides a pneumatic tire having an extruded sidewall that forms the increased rubber gage between the body ply and the belt package. In one embodiment, the extended sidewall extends all the way across the tire to connect both sidewalls. In another embodiment, each sidewall has an insert that extends partially across the tire to form a pair of opposed belt edge inserts that increase the rubber gage between the body ply and belt packages at the edges of the tire.
- The invention provides an improved pneumatic tire having a body, a belt package and a tread package. The improvement including a layer of rubber disposed between the body and the belt package wherein the thickness of the layer of rubber is between 0.5 millimeters and 1.5 millimeters.

- FIG. 1 is a cross sectional view of half of a pneumatic tire having the increased rubber gage between the body and belt package according to the concepts of the present invention with the other half of the tire being substantially a mirror image of the half depicted;
- FIG. 1A is an enlarged view of the encircled portion of FIG. 1;
- FIG. 2 is a cross sectional view similar to FIG. 1 showing an alternative embodiment of the present invention;
- FIG. 2A is an enlarged view of the encircled portion of FIG. 2;
- FIG. 3 is a cross sectional view similar to FIG. 1 showing another alternative embodiment of the present invention;
- FIG. 3A is an enlarged view of the encircled portion of FIG. 3;
- FIG. 4 is a view similar to FIG. 1 showing a further alternative embodiment of the present invention;
- FIG. 4A is an enlarged view of the encircled portion of FIG. 4;
- FIG. 5 is a view similar to FIG. 1 showing yet another alternative embodiment of the present invention; and
- FIG. 5A is an enlarged view of the encircled portion of FIG. 5.
- Similar numerals refer to similar parts throughout the drawings.
- The tire of the present invention is indicated generally by the
numeral 10 in the accompanying drawings. Tire 10 generally includes abody 12, abelt package 14, and atread package 16. As is known in the art,body 12 includes a pair ofsidewalls 18 havingbead rings 20 andapex fillers 22.

As is known in the art,belt package 14 includes a plurality of reinforcingcords 34 embedded within or substantially surrounded byrubber 35.Body 12 includes at least one layer ofbody cord 32 embedded within or substantially surrounded byrubber 33. In the preferred embodiment of the present invention,layer 28 has a thickness of between a first thickness less than 0.5 millimeters and a second thickness less than 1.5 millimeters as indicated by the dimension line labeled by the numeral 29 (FIG. 1A). In the embodiment of the invention depicted in FIG. 1,thickness 29 spaces thebody cords 32 from reinforcingcords 34 by a distance of between about 0.5 and about 1.5 millimeters as indicated bydimension line 30.Dimension line 30 includes theentire thickness 29 oflayer 28, a portion of therubber 33 that encasescords 32, and a portion of therubber 35 that encasescords 34. It has been found thatlayer 28spacing cords 32 fromcords 34 bydimension 30 improves the cornering characteristics oftire 10 while not degrading the rolling resistance oftire 10. Such results were unexpected because it was generally believed that the rolling resistance oftire 10 would increase withrubber layer 28 positioned betweenbody 12 andbelt package 14. In fact, tests show that the rolling resistance only undesirably increases oncethickness 29 oflayer 28 reaches 2 millimeters. It is thus an important aspect of the present invention thatthickness 30 remains between about 0.5 and about 1.5 millimeters. - Inserting
layer 28 intire 10 to form dimensions discussed above improves the cornering coefficient, tire vibrational levels, and coarse road noise oftire 10 while not significantly degrading the rolling resistance oftire 10.Layer 28 improves these characteristics independent of the tread pattern used withtire 10 and the aspect ratio oftire 10. - In accordance with another objective of the present invention,

Layer 28 may be manufactured separately frombody 12 andbelt package 14 and positioned in the desired position during the manufacturing process. In the preferred embodiment of the invention,layer 28 extends substantially the same width asbelt package 14.Layer 28 may, however, be formed in other widths. - An alternative embodiment of the tire having the increased rubber gage between the body and belt package is indicated generally by the numeral200 in FIGS. 2 and 2A. In accordance with one of the objectives of the present invention,
tire 200 includes extra rubber between reinforcingcords 34 andbody cords 32 such thatcords 32 are spaced fromcords 34 by about 0.5 and about 1.5 millimeters as indicated by thedimension line 30. The extra thickness of rubber in this embodiment of the invention is achieved by extendingrubber 35 surroundingcords 34 downwardly and extendingrubber 33 surroundingcords 32 upwardly. The proportions of the thickness ofrubber 33 andrubber 35 may vary with a preferred embodiment depicted in FIGS. 2 and 2A whererubber 33 is extended 40 to 60 percent of the distance. - Another alternative embodiment of the tire having the extra gage of rubber is indicated generally by the numeral300 in FIG. 3. In accordance with one of the objectives of the invention,
cords 32 are separated fromcords 34 by an extra gage of rubber such thatcords 32 are separated fromcords 34 by a distance between about 0.5 and about 1.5 millimeters as indicated by thedimension line 30. In this embodiment,distance 30 is achieved by extendingrubber 35 surroundingcords 34 downwardly until it abutsrubber 33encapsulating cords 32. - A further embodiment of the tire of the present invention is indicated generally by the numeral400 in FIGS. 4 and 4A. The structure of
embodiment 400 is similar to the structure oftire 10 depicted in FIGS. 1 and 1A except that the extra gage of rubber does not extend entirely acrosstread package 16. As shown in FIG. 4, the extra gage of rubber only extends partially acrosstread package 16 fromside wall 18 towards the center line (CL) oftire 400. In the preferred embodiment,gage 28 extends approximately two-thirds of the distance fromsidewall 18 to centerline CL.Extra gage 28 cooperates withrubber space cords 32 from cords 34 a distance of between about 0.5 and about 1.5 millimeters at their widest portion with the distance tapering as the cords move toward the center oftire 400. - FIG. 5 depicts yet another embodiment of a tire of the present invention as indicated generally by the numeral500.
Tire 500 has a similar structure to tire 10 except thatrubber 28 is formed integrally with the rubber ofsidewall 18 and extends entirely across tire from an inner location indicated by the numeral 502 to the opposite inner location on the other side of the tire.Layer 28 thus may be extruded or calendered as a single layer of rubber and draped entirely across the width oftire 500.Layer 28 is configured to provide similar spacing astire 10 depicted in FIGS. 1 and 1A. - Accordingly, the improved tire having increasing gage below the belt package is simplified, provides an effective, safe, inexpensive, and efficient device which achieves all the enumerated objectives, provides for eliminating difficulties encountered with prior devices, and solves problems and obtains new results in the art.
