  • Publication number: 20230046498
    Abstract: A non directional pneumatic tire is provided for an agricultural irrigation system. The tire includes first and second side walls and a radially outer wall defining an internal inflation chamber. A non directional tread pattern is defined on the tire and includes a plurality of longitudinal protrusions positioned substantially parallel to a rotational axis of the tire. The longitudinal protrusions are arranged in first and second rows extending from the first and second side walls toward and across the equatorial plane of the tire. The longitudinal protrusions of the first and second rows circumferentially alternate with each other and there is a circumferential spacing between adjacent longitudinal protrusions at the equatorial plane so that no portion of one longitudinal protrusion circumferentially coincides with or overlaps another.

  • Publication number: 20230042193
    Abstract: A non-pneumatic tire includes a lower ring having a first diameter and an upper ring having a second diameter greater than the first diameter. The upper ring is substantially coaxial with the lower ring. The non-pneumatic tire further includes support structure extending between the lower ring and the upper ring and a tread layer formed of a rubber material. The non-pneumatic tire also has a sidewall formed of the rubber material and extending seamlessly from the tread layer on a first side of the non-pneumatic tire.

  • Publication number: 20210387481
    Abstract: A non-pneumatic or pneumatic tire includes an area for tire indicia or markings. The tire includes a hub region and a tread layer. The tread layer of the tire has a shoulder with a cut out extending either partially or entirely around the shoulder of the tire tread layer. The angle of the notched or beveled portion is 45-135° with respect to an axial direction along the tread layer shoulder, and at least one indicia disposed on the at least one flat surface. The placement of the markings may be radially along the surface of the cut out portion or axially along the surface of the cut out portion. The markings may be recessed, stamped, molded, painted or applied with ink to the cut out portion. Alternatively, the indicia or marking may be applied to a decal and applied to the cut out portion.

  • Publication number: 20160001608
    Abstract: Various embodiments of a tire having a rim guard are disclosed. The rim guard may be configured to have reduced deflection and/or strain relative to the remainder of the tire's sidewall. As a result, decorative decals applied to the rim guard may be less likely to crack, disbond, or otherwise become damaged or deformed, leading to loss of function and/or detachment of the decal from the tire.

  • Patent number: 9079459
    Abstract: This application discloses a tire comprising a circumferential tread including at least one tread element having a top surface, at least one edge, and at least one chamfered surface extending between the top surface and the edge. The chamfered surface is oriented at an angle relative to the top surface of the tread element that varies along the length of the chamfered surface. Alternatively, the chamfered surface may have a width and a height that vary along their respective lengths.
