Abstract: As shown in FIGS. 1 and 2, in a pneumatic tire of the present invention, block-shaped land portions 18 are divided by main grooves 14 and lug grooves 16 on the tread 12 of a studless tire 10 and a plurality of transverse sipings 20 is formed on each of the block-shaped land portions 18. Each sipings 20 is formed from a first linear portion 20A, a second linear portion 20B, and a sloping line portion 20C. The first linear portion 20A essentially extends in a direction perpendicular to the surface 18A of the block-shaped land portion 18 and contacts the surface 18A, the second linear portion 20B essentially extends in a direction perpendicular to the surface 18A and is separated from the surface 18A, and the sloping line portion 20C inclines to connect the ends of the first linear portion 20A and the second linear portion 20B. In each of the sipings 20, the position D1 of the sloping line portion 20C is set to 10% to 60% of the siping depth D. As a result, deterioration of ground-contacting performance when the number of sipings is increased is prevented. In this way, wet grip performance, braking performance on ice, traction performance, and irregular wear resistance can be improved.

Abstract: A method for changing the residual aligning torque (RAT) of a pneumatic tire by forming angled sipes in certain of the tread blocks in at least a pair of circumferentially extending ribs, each rib being located on an opposite side of the mid-circumferential plane of the tire. The sipes in the tread blocks in one of the ribs are formed at an inclined angle opposite to the inclined angle of the sipes in the tread blocks in the opposite rib. The RAT can also be changed by varying the depth and width of the opposed angled sipes.

Abstract: A tyre includes a tread band having at least two substantially parallel longitudinal grooves and at least one series of transverse grooves crossing the longitudinal grooves. The transverse and longitudinal grooves delimit at least two rows of shoulder blocks and at least one row of centre blocks. The transverse grooves have at least two transverse channels, each including an outer end stretch in an orientation substantially perpendicular to an equatorial plane of the tyre and a curvilinear connecting stretch close to the equatorial plane. The joining of laterally-opposite transverse channels gives each transverse groove a continuous course. At least one transverse channel of at least one of the transverse grooves also includes an inner end stretch. The connecting stretch interconnects the outer end stretch with the inner end stretch in a continuity relationship. The inner end stretch penetrates a center block but does not cross any other of the transverse grooves such that the center block is a single element defined by the longitudinal grooves extending between two contiguous transverse grooves.
