摘要： A tire is disclosed having a tread extending from a first tread edge to a second tread edge and having a plurality of blocks defining a plurality of lateral grooves. The lateral grooves have a groove bottom defining a radial groove depth. A first biting side extends outwardly from the groove bottom to a first biting edge, and a first non-biting side extending outwardly from the groove bottom to a first non-biting edge. At least one peak is disposed in at least one of the lateral grooves. The peak extends outwardly from the groove bottom and terminates radially at an outer end and axially at a distance from the equatorial plane less than or equal to one half of the tread width. The peak has a height between 25 percent and 75 percent of the depth of its lateral groove. Multiple peaks may be disposed within a groove.

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.

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.
