Publication number: 20160159162Abstract: A pneumatic tire for use on row-crop field sprayers having lugs configured for providing improved traction, load-handling capability, and stability. The leading edge of each lug is curvilinear such that outside corners are absent. Elimination of outside corners removes stress concentration points that would otherwise degrade tire performance under the conditions of high loading and fast speed. The lugs provide a significant load-carrying capacity without sacrificing attributes such as wet and dry traction, tread cleaning and hard surface roading.Type: ApplicationFiled: February 10, 2016Publication date: June 9, 2016Inventors: Mark L. Bonko, Timothy Michael Rooney

Patent number: 5509456Abstract: An apparatus (10) for inflating larger tubeless tires (80), such as those utilized on farm tractors, includes a segmented manifold (104) which is expandable radially to accommodate different sizes of tires. The segmented manifold (104) includes outlet holes (36) from which pressurized gas may exit to inflate the tire (80). The holes (36) have centerlines which make angles generally between 40.degree. and 75.degree. with a plane containing the manifold (104). The angled holes (36) direct the pressurized gases exiting the manifold in optimum directions to expand the tire sidewall against the wheel flange (92) to assist in sealing the tire beads against the wheel (82).Type: GrantFiled: April 18, 1994Date of Patent: April 23, 1996Assignee: The Goodyear Tire & Rubber CompanyInventors: Mark L.

Patent number: 5337814Abstract: An improved pneumatics radial drive tire 10 for agricultural use under dry and wet or moist soil conditions requiring a tire with high flotation and deep tread characteristics is described. The improvement comprises utilizing a tread 13 with a net-to-gross ratio in the range of 15 to 25% and where the tread 13 has lugs 18A, 18B that are greater than 150% of standard R1 lug and greater than 75% but less than 95% of an R2 lug. The lugs when incorporated in a 20.8 R38 radial tire are designed to support and carry for extended distances a dynamic load bearing weight of 170% of the Tire and Rim Association's recommended load on paved surfaces without lug failure.Type: GrantFiled: January 21, 1992Date of Patent: August 16, 1994Assignee: The Goodyear Tire & Rubber CompanyInventor: Mark L.

Patent number: 5337816Abstract: An improved pneumatic agricultural tire (10) having a maximum section width (SW), an equatorial plane (EP) and a rim diameter (D) of 24 (61 cm) inches or greater is described. The tire (10) is particularly well suited for use as an irrigation tire. The tire (10) comprises a casing (12) having a cord reinforced rubber coated carcass (14) and a rubber tread (40) disposed radially outwardly of the carcass. The tread (40) includes an inner tread (42) and tread lugs (44,44L). The lugs (44,44L) are of a depth of less than R1, (R1 being defined as about 1.52 inches or about 3.9 cm) preferably about 80% of the R1 depth. The lugs extend axially inward a distance of 25% to 60% of the section width from an axially outer end to an axially inner end and less than a majority of the lugs extend across the equatorial plane of the tire. The tread (40) has a net-to-gross ratio of less than 30%. The tread lugs each have a centerline located midway between leading (52) and trailing edges (54) of the lug (44,44L).Type: GrantFiled: November 20, 1992Date of Patent: August 16, 1994Assignee: The Goodyear Tire & Rubber CompanyInventors: Mark L. Bonko, Loran C. Lopp, Jr.

Patent number: 5188683Abstract: A pneumatic tire particularly suited for agricultural or logging use is described. The tire has lateral-edge lugs with projections extending axially outward of the tire's maximum section width. The projections are radially inward of the ground contacting surface of the lug while also being radially outward of the inner tread surface. The projection extends axially inwardly and radially outwardly from the axially-outer-limit to the ground contacting surface of the tread lug. The projection further extends generally axially and radially inwardly from the axially-outer limit of the projection to the lateral edge of the inner tread surface from which the lug extends.Type: GrantFiled: April 22, 1991Date of Patent: February 23, 1993Assignee: The Goodyear Tire & Rubber CompanyInventor: Mark L. Bonko

Patent number: 5046541Abstract: A tire for tractors and other off-the-road vehicles which exhibits good traction, vibration and cleaning characteristics. The tire has a tread with two sets of primary lugs (34, 38) sets of secondary lugs (70, 72). The one set of primary lugs (34) are spaced about the tread (32) and extend from the first lateral tread edge (36) to an inner end which does not extend beyond the equatorial plane (EP). The other set of primary lugs (38) extend from the second lateral edge (40) and are opposite in hand to the first set of primary lugs. The first and second sets of secondary lugs are spaced from the first and second lateral edges respectively with the second set (72) being opposite in hand to the first set (70) of secondary lugs. Each lug of the first set of secondary lugs is located between a pair of primary lugs of the first set as are each lug of the second set of secondary lugs of the second set located between a pair of primary lugs of the second set.Type: GrantFiled: October 11, 1989Date of Patent: September 10, 1991Assignee: The Goodyear Tire & Rubber CompanyInventor: Mark L.

Patent number: 5016696Abstract: A tread element (314) is located between the axially outer end of the lugs of the tread and lateral tread edge (310) of the tire (300). The tread elements (314) provide a flexing action for breaking the soil bond or adhesion to the tread of the tire. The tread elements (314) are not located in the discharge path but are adjacent to the discharge area in order to eject or remove soil, mud, sand etc., therefrom.Type: GrantFiled: October 11, 1989Date of Patent: May 21, 1991Assignee: The Goodyear Tire & Rubber CompanyInventors: Mark L. Bonko, Loran C. Lopp, Jr.

Patent number: 5010935Abstract: A pneumatic tire for agricultural use has a tread including an inner tread surface and a plurality of spaced tread lugs (170). The tread lug (170) for use with off-the-road or agricultural, has at least one sidewall in cross-section having two different angular inclinations. The sidewall has a first straight portion (202) which extends radially inwardly from an edge (204) of the ground engaging surface (200) of the lug (170) at a first angular inclination (b) with respect to the radial direction. A second straight portion (208) extends radially inwardly at a second angular inclination (c) with respect to the radial direction, while a first concaved curved portion (212) extends from the first straight portion (202) to the second straight portion (208). A second concaved curved portion (214) then extends radially inwardly from the second straight portion (208) to an inner tread surface (151).Type: GrantFiled: October 11, 1989Date of Patent: April 30, 1991Assignee: The Goodyear Tire & Rubber CompanyInventors: Mark L. Bonko, Loran C. Lopp, Jr.

Patent number: 4982773Abstract: A pneumatic tire design primarily for off road use has a pair of bead regions, a ground-engaging tread, and a pair of sidewalls between the beads and the tread. The inner tread surface between tread lugs and the tread edges has curvature in both the axial and circumferential directions. A series of projections are integral with a sidewall and are arranged in a circular pattern. Each projection is axially adjacent and axially outward of a portion of the inner tread surface and outwardly of the sidewall and is interposed between lateral tread lugs. The projections and lateral tread lugs are positioned to provide a means for deflecting radially directed debris away from the sidewalls. The sidewalls are protected without requiring circumferentially continuous projections.Type: GrantFiled: April 3, 1989Date of Patent: January 8, 1991Assignee: The Goodyear Tire & Rubber CompanyInventor: Mark L.
