Abstract: A non-pneumatic tire (100) having a pair of opposing annular support structures (102, 104) that extend circumferentially around the tire. Each support structure (102, 104) includes a radially-inner joint (120), a radially-outer joint (122), and a pair of support legs (132, 134) connected with a central joint portion (148). An annular band connects with the support structures (102, 104).

Abstract: The invention includes tire treads, tires incorporating such treads, and methods for forming the same with a reduced undertread thickness. The treads include a length, a thickness, and a width, the width extending transverse to a direction of the tread thickness and a direction of the tread length. The treads further include a void extending into the tread thickness by a depth to a bottom side of the void, the void having a length and opposing sides spaced apart to form a void width. Yet further the treads include a ridge arranged along the bottom side of the void and protruding outward from the bottom side by a ridge height, the ridge also having a ridge length extending at least substantially continuously along the substantial length of the void.

Abstract: A device and method for manufacturing features into the tread of a tire are provided. The device and method provide for manufacturing tread features of various shapes and sizes. The tread features may be recessed, protruding, or flush with respect to the surrounding tread surface. The device and method may be used for both new tire constructions as well as retreading operations.

Abstract: A run-flat support ring, which is a component mounted upon a rim inside a tire to extend the distance the tire may travel at reduced or zero inflation pressure, is provided having one or more features that improve the process of mounting the support ring onto a rim and better tolerate variations, within manufacturing tolerances, in the respective diameters of the rim and the support ring.

Abstract: An assembly comprising a rim having a substantially cylindrical bearing surface having at least one depression therein, and an annular run-flat support mounted on the bearing surface. The radially inner surface of the support further comprising a protuberance to engage the depression in the rim, and wherein a radially innermost base portion of the support includes a plurality of substantially circumferentially oriented reinforcement elements. The reinforcement elements are axially spaced apart, and the reinforcement elements are absent in an axial portion of the base portion radially outward of the protuberance.

Abstract: A run-flat support ring, which is a component mounted upon a rim inside a tire to extend the distance the tire may travel at reduced or zero inflation pressure, is provided having an integrated shelf design that enhances the handling characteristics of the support ring under run-flat conditions and may also lower the overall mass of the support ring in certain applications. In addition, the support ring has one or more features that improve the process of mounting the support ring onto a rim and better tolerate variations, within manufacturing tolerances, in the respective diameters of the rim and the support ring.

Abstract: A run-flat support ring, which is a component mounted upon a rim inside a tire to extend the distance the tire may travel at reduced or zero inflation pressure, is provided having an internal fin design that improves the rolling resistance of the support ring without sacrificing the overall load bearing and handling characteristics. Certain embodiments may also include one or more features that improve the process of mounting the support ring onto a rim and better tolerate variations, within manufacturing tolerances, in the respective diameters of the rim and the support ring.
