Patent number: 12208648Abstract: 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.Type: GrantFiled: November 1, 2022Date of Patent: January 28, 2025Assignee: Bridgestone Americas Tire Operations, LLCInventors: Bill J. Wallet, John J. Regallis, Jeffrey D. Parker, Nobuo Shimizu, Andrew T. Miklic, Keith A. Dumigan

Publication number: 20230042193Abstract: 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.Type: ApplicationFiled: November 16, 2020Publication date: February 9, 2023Inventors: Richard S.

Publication number: 20210387481Abstract: 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.Type: ApplicationFiled: October 9, 2019Publication date: December 16, 2021Inventors: Martin A.

Publication number: 20160001608Abstract: 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.Type: ApplicationFiled: June 24, 2015Publication date: January 7, 2016Inventors: David G. Abdallah, JR., Natalie V. Weingart, Paula R. Lundgren, Keith A. Dumigan
