20150013863 | Tire With Pre-Formed Tread And Method Of Making Same - Methods of making tires with features such as ribs, lugs, or tread blocks include shaping at least one feature onto an uncured tire tread prior to vulcanization. One aspect of these methods may include shaping a feature onto the tread while the tread is associated with the tire. Shaping devices may include shaping rollers, stitching rollers, pre-molds, and annular, curved, or flat stamping plates. An additional aspect of these methods may further reduce the amount of air between a tread and carcass prior to vulcanization. These methods may be used in conjunction with manufacturing processes used on various types of tires, and are particularly suitable for use in large tire manufacturing processes. | 01-15-2015 |
20150013864 | Tire With Pre-Formed Tread And Method Of Making Same - A green tire includes a carcass and a pre-shaped tread. The carcass includes a pair of annular beads and at least one body ply extending between the pair of annular beads. The carcass further includes a circumferential belt. The pre-shaped tread includes a plurality of tread segments, wherein each of the plurality of tread segments includes at least one bar and at least one void. | 01-15-2015 |
20150053318 | AGRICULTURAL TIRE TREAD - 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. | 02-26-2015 |
