摘要： A tire includes a pair of sidewalls and a circumferential tread having a zigzag circumferential groove. The zigzag circumferential groove is defined by a groove bottom, a pair of groove walls, and a pair of groove edges defining an intersection between each groove wall and a top surface of the circumferential tread, wherein each of the groove edges smoothly widens and narrows along the groove. The circumferential tread has a first circumferential pitch with first and second circumferential pitch lengths. The first circumferential pitch includes a first zigzag circumferential groove segment and a second zigzag circumferential groove segment that form a first intersection angle. The second circumferential pitch includes a third zigzag circumferential groove segment and a fourth zigzag circumferential groove segment that form a second intersection angle different from the first intersection angle.

摘要： An agricultural tire has an equatorial plane separating first and second sides. First and second inner sixths of the treads extend between the equatorial plane and circumferential reference planes disposed axially one-sixth of a tread width on either side of the equatorial plane. First and second middle sixths of the tread extend between inner circumferential planes and middle circumferential reference planes one-sixth of the tread width from the inner circumferential reference planes. Outer sixths extend between the middle circumferential reference planes and outer circumferential reference planes disposed one-sixth of the tread width from the middle planes. Net tread volume ratio is approximately 40 percent, where between 36 and 39 percent of lug volume is in the inner sixths, between 32 to 35 percent in the middle sixths, and 27 to 30 percent in the outer sixths of the tread.

摘要： A pneumatic tire includes a tread portion having a tread groove having a groove bottom and groove sidewalls. A row of rounded stone ejectors are spaced apart along a length of the groove. Each rounded stone ejector has a base attached to the groove bottom and independent from the groove sidewalls. Each rounded stone ejector has a rounded peak and is continuously tapered from the base to the rounded peak.

摘要： A pneumatic agricultural tire includes first and second rows of angled lugs. Each lug is provided with a leading wall rising up from a tread floor to a leading edge of the lug surface. The leading wall has a wedge shaped leading nose rising up from the tread floor and sloped in the trailing direction so that ground stubble is engaged by and pushed aside by the wedge shaped leading nose thereby reducing stubble damage at a root of the leading wall.
