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 lamella for use in a vehicle tire vulcanization mold has projections and depression, wherein the height of the projections and the depth of the depressions extend substantially parallel to a peripheral surface of the tire tread of the vehicle tire to be molded in the vulcanization mold. Each one of the projections has a highest point-shaped location or top. Each one of the depressions has a lowest point-shaped location or crater. The projections and depressions are distributed according to a substantially uniform areal division. The areal division is defined by dividing lines extending in a dividing plane preferably centrally positioned between a first plane defined by the tops and a second plane defined by the craters. The dividing lines are comprised of three sets wherein the dividing lines within each one of the sets extend parallel to one another and wherein the dividing lines of different ones of the sets intercept one another at an angle of substantially 60null so that a grid of triangles is formed. Instead of point-shaped highest or lowest locations, line-shaped highest and lowest locations can be provided.

Abstract: The lamella fine cut-outs provided in profile elements of the tread surface of a tire, have three-dimensionally structured wall regions. Such wall regions restrict relative movements of the mutually facing wall regions in lateral as well as in radial direction. In such manner there are improved the travel characteristics as well as the wear characteristics like break-outs and irregular wear of such lamella tires.

Abstract: A pneumatic tire tread having traction groove formations designed to limit stone pickup and retention in service is disclosed, together with a mold insert construction therefor. Each such formation consists of increased depth groove section in one wall of which is provided an annular ridge surrounding an axial depression, and in the other wall of which is provided a registering annular channel surrounding an axial protuberance. ''''Dimpled'''' projections of the disclosed mold insert blades are used to create the formations, each of which ''''dimples'''' has the appearance, at one face of the respective blade, of an annular ridge surrounding a central depression, and at the reverse blade face, of a central protuberance surrounded by an annular channel. Advantages are greater blade strength and easier extraction of the cured tire from the mold, as well as enhanced stone rejection.
