Embodiment Construction

[0020] For purposes of describing the invention, reference will now be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

[0021] As mentioned above, the resistance of a tire to the impact of road hazards can be measured using a breaking energy (BE) test, such as FMVSS 119 or DOT 119 (which are well known and published). An a...

Abstract

Pneumatic tire for heavy duty vehicles having a crown portion comprising two working plies (114,116) and a breaker ply (120) radially outward of the carcass body ply wherein the breaker ply (120) comprises a plurality of breaker ply reinforcement elements (122) having a length L of no more than 155 mm, at an angle of 5 to 60 degrees.

Description

[0001] priority statement [0002] This application claims priority under 35 U.S.C. §119 to PCT / US15 / 065968, filed December 16, 2015. technical field [0003] The invention concerns tires with unique reinforcements in the crown portion. Background technique [0004] A tire's resistance to road hazards is an important aspect of temporal performance, along with properties such as rolling resistance, traction, wear, and the like. As used herein, road hazard performance refers to the ability of a tire to impact obstacles in the road without suffering critical structural damage along the crown portion of the tire. For example, during operation, tires may encounter rocks, holes, or other hazards that have the potential to damage reinforcements in the crown portion of the tire. [0005] A well-known test for road hazard performance is called the Breaking Energy Test (BE Test), which is described by the United States Government as FMVSS 119 or DOT 119. In this test, a steel plun...
