    Abstract: The present invention is directed towards speckled tire treads for tires. Specifically, the speckled tire tread includes a primary tread compound that serves as a matrix in which is distributed discrete particles of one or more secondary tread compounds, at least one of the compounds is a different color than the other tread compound(s) so as to be visually distinguishable. For example, the primary tread compound may include carbon black pigment and be black in color while the secondary tread compound can include one or more pigments to provide the particles with non-black color. Thus, the colored particles have a visually distinguishable color from that of the primary tread composition. Additionally, at least a portion of the particles may be situated for viewing on a running surface of the tire tread so that a subject can visually distinguish between the compounds, and such observed compounds may provide a different tire performance characteristic(s).

    Abstract translation: 本发明涉及用于轮胎的有斑点的轮胎胎面。 具体地，有斑点的轮胎胎面包括作为基质的初级胎面组合物，其中分散有一种或多种次级胎面胶料的离散颗粒，至少一种化合物与另一种胎面胶料的颜色不同， 在视觉上可区分。 例如，主胎面化合物可以包括炭黑颜料并且是黑色的，而第二胎面胶可以包括一种或多种颜料以提供非黑色的颗粒。 因此，着色颗粒具有与初级胎面组合物的​​颜色可视地区分开的颜色。 此外，可以将至少一部分颗粒定位用于在轮胎胎面的行进表面上观察，使得受试者在目视上区分化合物，并且这些观察到的化合物可提供不同的轮胎性能特征。

    Abstract: A high performance tire includes a carcass provided with at least one carcass ply, a belt including two or more layers of reinforcing cords parallel to each other in a layer and crossed with respect to those of an adjacent layer, applied circumferentially on the carcass, a radially-external layer of circumferentially-oriented reinforcing cords applied on the belt, and a tread band comprising an underlayer and an external layer. The underlayer may have a hardness which is substantially constant over a temperature range between 23null C. and 100null C. The underlayer may also have an elastic modulus which is substantially constant over a temperature range between 70null C. and 100null C. Additionally, the underlayer may be made from an elastomer compound comprising reinforcing fibers and hardening resins. Further, the underlayer may have a hardness and an elastic modulus which remain substantially constant between 70null C. and 100null C. A method for making the tire is also disclosed.

    Abstract: Disclosed is an improved structure for rubber bodies such as pads on track units or tires on road wheels for tracked vehicle such as tanks. The rubber bodies have an array of bores with metallic inserts recessed in the bores. The inserts stiffen the pad or tire to reduce deformation under load and the heat produced thereby, and also transfer the heat to the surrounding air. In one embodiment, the inserts are cups closely fitting in the bores and having fins or other protrusions extending from the cup into the rubber body. In other embodiments, the inserts comprise heads near an exposed surface of the rubber body and shanks extending from the heads to a metal substrate underlying the rubber body and forming part of the track unit or road wheel.
