    Abstract: A method for reducing tire microsliding includes defining a rotation point and rotating a cross section profile about it. A cross section of a radially-external reference profile of a tread band includes a first rectilinear segment near at least one circumferential rib of a first shoulder portion. The first rectilinear segment extends axially outward beyond a corresponding shoulder edge point. A cross section profile of the at least one circumferential rib of the first shoulder portion includes a second rectilinear segment. The rotation point is on the first rectilinear segment, either the corresponding shoulder edge point itself or axially outward of it. The cross section profile of the first rectilinear segment is rotated to define the cross section profile of the second rectilinear segment, so that an axially-inner end of the second rectilinear segment is closer to the carcass structure than an axially-inner end of the first rectilinear segment.

    Abstract: A heavy duty pneumatic tire having improved resistance to uneven tread wear includes a tread portion provided with an axially outer longitudinal main groove and an axially inner longitudinal narrow groove, each extending circumferentially about the tire to define a narrow rib therebetween, the axially inner edge of the narrow rib being chamfered by a slope. In the tire meridian section, the slope is straight or concave. The axial width of the axially inner longitudinal narrow groove is in the range of from 0.5 to 2.5 mm. The axial width (W3) of the slope measured between the upper and lower edges thereof is in the range of from 0.3 to 0.8 times the axial width (W2) of the narrow rib, and the radial height (H2) of the slope measured between the upper and lower edges is in the range of from 0.3 to 0.8 times the depth (H1) of the axially inner longitudinal narrow groove.
