Abstract
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.
