摘要： A pneumatic tire (10) is disclosed comprising a carcass (22) and a belt structure (40). The belt structure (40) comprises a plurality of belt layers that include at least one spiral belt layer (60) and at least one zigzag belt layer (70). Each of the at least one spiral belt layers (60) has cords arranged at an angle of 5° or less with respect to an equatorial plane of the pneumatic tire (10) and each of the at least one zigzag belt layers (70) has cords arranged at an angle in a range of from of 2° to 40°, alternatively from 5° to 30°, with respect to the equatorial plane of the pneumatic tire (10) and extending in alternation to turnaround points at each lateral edge of the belt structure (40). A first belt layer of the plurality of belt layers located radially outward of the carcass (22) is one of the at least one spiral belt layers (60). The first belt layer has an axial width less than the axially widest belt layer of the plurality of belt layers. The pneumatic tire (10) further comprises a tread (20) comprising two or more main grooves (17a, 19a, 17b, 19b) extending circumferentially continuously around the pneumatic tire (10) and defining a plurality of ribs (25a, 23a, 21, 23b, 25b) that include an axially outermost rib (25a, 25b) on each lateral side of the tread (20). At 10% to 100% of the rated inflation pressure of the pneumatic tire (10) and no load, each of the two axially outermost ribs (25a, 25b) is radially raised in relation to a respective next nearest rib (23a, 23b) located axially inward of the respective axially outermost rib (25a, 25b).

摘要： A method is disclosed comprising placing a tire building drum of a tire building machine in a position relative to a machine vision system, the machine vision system being configured to generate a three dimensional image of the tire building drum as a breaker or a green rubber tread is applied to the tire building drum. In a first aspect, the method comprises: setting a radius of the tire building drum to a known radius; and attaching a calibration fixture to the tire building drum, where a position of a plurality of surfaces of the calibration fixture are known relative to a bottom surface of the calibration fixture; obtaining an axial image trace across the calibration fixture attached to the tire building drum; and mapping, from the axial image trace, a position in an array column of individual ones of a plurality of pixels to corresponding radius values relative to a center of the tire building drum for the machine vision system to be used to generate a subsequent three dimensional image. In a second aspect, the method comprises: identifying at least one edge of the tire building drum in the three dimensional image, wherein a location of the at least one edge comprises a corresponding at least one calibrated edge position; and storing the at least one calibrated edge position of the tire building drum for verification of a position of the tire building drum. Furthermore, an apparatus for practicing this method is disclosed.

摘要： A tire (10) for a vehicle is disclosed. The tire (10) comprises a circumferential tread portion (11) comprising a tread pattern exhibiting at least a first pitch pattern (20) and a second pitch pattern (22). In one aspect, each of said first and second pitch patterns (20, 22) comprises a center block (26) and two side block alignments (28) which are inclined with respect to one another and extend from the center block (26), the first pitch pattern (20) including a first pitch length (Li) and a first number of blocks (30), the second pitch pattern (22) including a second pitch length (L 2 ), which is shorter than the first pitch length(L 1 ), and a second number of blocks (32) which is greater than the first number of blocks (30). In another aspect, the first pitch pattern (20) has a first pitch length (Li) and a first number of first tread elements (30) arranged in a V shaped pattern across the lateral width of the tread portion (11), the second pitch pattern (22) has a second pitch length (L 2 ), which is shorter than the first pitch length (L 1 ), and a second number of second tread elements (32) arranged in a V shaped pattern across the lateral width of the tread portion (11). In yet another aspect, the first pitch pattern (20) includes a first group of identical blocks (30) which comprise a first center block (26) and two side block alignments (28) which are inclined with respect to one another, and a first number of identical blocks (30); and the second pitch pattern (22) includes a second group of identical blocks (32) which comprise a second center block (26) adjacent to the first center block (26), two side block alignments (28) which are inclined with respect to one another, and a second number of identical blocks (32), the second number of identical blocks (32) being greater than the first number of identical blocks (30).
