20120298269 | COMMERCIAL TRUCK TIRE - A tire includes a circumferential regional tire tread having a central region and first and second shoulder regions adjacent the central region. A circumferential array of spaced apart shoulder sipes is formed within one or both of the shoulder regions, each of the shoulder sipes having a depth in an unworn tire tread condition within a depth range of from 1 mm to 3.5 mm, and each shoulder sipe having a longitudinal axis oriented in a substantially axial direction within a range of between 20 degrees of the tire axial direction. The shoulder sipes each include a first and a second straight segment intersecting at an end-to-end intersection with respect to each other at an intersection angle. The first and second straight segments of each shoulder sipe incline in opposite directions from the end-to-end intersection and the end-to-end intersection of each shoulder sipe is located at a circumferential shoulder groove within a respective shoulder region. | 11-29-2012 |

The central rib has a plurality of circumferentially spaced sipes arranged in a first circumferential row and a second circumferential row. The sipes of the first row originate at the first circumferentially continuous groove and the sipes of the second row originate at the second circumferentially continuous groove. The sipes of both the first and second rows extend axially inward to a circumferentially extending and continuous variable center groove. The variable center groove has a minimum circumferentially extending opening at a radially outermost portion. As the tread wears and the radially outermost portion of the tread moves radially inward, the circumferentially extending opening of the variable center groove widens to a maximum circumferentially extending opening greater than the minimum circumferentially extending opening. | 01-17-2013 |
20130061992 | HIGH MILEAGE TRUCK TIRE TREAD - A vehicle wheel tire having a symmetrical five rib tread construction with adjacent tread ribs comprising the tread separated by circumferential grooves. The intermediate tread grooves have an axial width wider than an axial width of the shoulder grooves and a center rib has an axial width wider than the axial widths of the intermediate ribs and the shoulder ribs. The axial width of the center rib, intermediate ribs, and shoulder ribs are within a prescribed preferred range of a total tread axial width and the axial width of each intermediate groove is within a prescribed preferred range of total tread axial width. | 03-14-2013 |
20130061993 | COMMERCIAL TRUCK STEER TIRE TREAD - A vehicle tire tread includes a circumferential spaced apart array of discrete tie-bar block elements within a circumferential tread groove, each tie-bar block element having a circumferentially oriented bisecting cut dividing the tie bar into opposed tie-bar components. The opposed tie-bar components operatively flex and converge axially when present within a rolling tire footprint to close the radially outward cut segment and resume a nominal separation dimension when outside a rolling tire footprint. The bisecting cut within each tie-bar block element further forms at a radially inward end a large diameter fluid conducting channel extending through the tie-bar block element to allow the passage of fluid along the circumferential groove, unobstructed by the array of tie-bar block elements. | 03-14-2013 |
