摘要： A mold for molding a tire tread comprises a plurality of mold segments. Each of the plurality of mold segments includes an integer number of tread pitch repetitions. The plurality of mold segments are structured to be coupled to each other end-to-end so as to form the mold such that the mold includes an integer number of tread pitches. The mold also includes at least one mold end segment positioned on at least one end of the mold and has a mold end segment length shorter than a length of each of the plurality of mold segments.

摘要： A contour CL of a carcass 12 includes a curved portion 44 and an inversely curved portion 46. A boundary between the curved portion 44 and the inversely curved portion 46 is an inflection point PV. A part or an entirety of the curved portion 44 is represented by a first arc. A part or an entirety of the inversely curved portion 46 is represented by a second arc. The first arc and the second arc are tangent to each other at the inflection point PV. A ratio (X/W) of a distance X in an axial direction to a distance W in the axial direction is not less than 70% and not greater than 85%. A ratio (Y/H) of a distance Y in a radial direction to a distance H in the radial direction is not less than 15% and not greater than 22%.

摘要： A tyre includes a toroidal ring-shaped carcass structure with at least one carcass ply associated with at least one annular fixing structure, as well as a tread band positioned radially externally with respect to the carcass structure. The annular fixing structure includes a radially inner and axially inner surface and a radially inner and axially outer surface, the surfaces being substantially opposed to each other. The radially inner and axially inner surface and radially inner and axially outer surface are shaped by successive application of a first squeezing pressure produced by a first surface and a second surface of a curing mould that are brought towards each other, as well as a second squeezing pressure produced by bringing the first and second surfaces closer together. The radially inner and axially inner surface and/or radially inner axially outer surface have a shape that includes air evacuation channels.

摘要： The invention provides a method of mounting a device to a tire so that the device is mounted on a flat surface. The invention includes a shaped rubber patch having a flat mounting surface and a doubly curved lower surface. The shaped rubber patch is mounted inside the tire in such a way that the curved lower surface mates to the tire sidewall so that the device can be mounted on a flat surface. Because the curved lower surface of the patch mates with the tire curvature, a better attachment interface is provided.
