20100243118 | Pneumatic tire for use on row-crop field sprayers and other like farm machinery - 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. | 09-30-2010 |

20100059157 | MULTI-PURPOSE TIRE - A tire has a circumferential tread, the tread including shoulder tread regions configured for off-road performance separated by and interlocking with a center tread region configured for on-road performance. The shoulder tread regions are defined by a repeating pattern of two or more distinct shoulder tread elements and the center tread region is defined by a repeating pattern of two or more distinct center tread elements. The shoulder tread elements each have a ground contacting surface area greater than a ground contacting surface area of the center tread elements. The center tread elements extend at a relatively greater angle of inclination with respect to an equatorial centerplane of the tire and the shoulder tread elements extend at a relatively lesser angle of inclination with respect to the centerplane. The center tread elements and the shoulder tread elements are irregular and asymmetrical about a longitudinal central axis and a transverse central axis and, together, total five or more (three in the center tread region and two in the shoulder tread region) tread blocks of mutually distinctive geometric shape. | 03-11-2010 |

20090194212 | TIRE TREAD DISCHARGE GROOVES WITH TEXTURED BASES - The present invention is directed to a pneumatic tire comprising an axis of rotation and a tread. The tread has a plurality of traction elements and a discharge groove. The discharge groove has a base interposed between radially extending sides formed by side walls of the traction elements. The base of the discharge groove defines a matrix of circumferentially extending rectangular ramp structures. One ramp structure of the matrix extends circumferentially, from a radially inner first end portion, in a direction of rotation of the tire and radially outward to a radially outer second end portion. The radially outer second end portion defines an edge portion extending parallel to the axis of rotation of the tire. The edge portion improves traction of the tire and evacuation of the discharge groove. | 08-06-2009 |
