Method for controlling the symmetry of the footprint area of a tyre miming on a straight trajectory with camber angle different from zero, wherein the method comprises the steps: —reducing the contact pressure of the tyre (2) on the footprint area at an inner shoulder (in case of negative camber) or at an outer shoulder (in case of positive camber); —disposing any medium line (Im) of the tread band (9) placed in correspondence with the footprint area substantially parallel to the ground; the invention also defines a tyre and a wheel for motor-vehicles, wherein the medium line (Im) of the tread hand (9) and the rotation axis (X-X) of the tyre (2) form an angle (a) substantially equal in absolute value to the camber angle (β); the invention also encompasses a process for manufacturing such tyres, wherein a green tyre with symmetric outer profile is deformed during the vulcanising and moulding step until a predetermined angle (a) different from zero is formed between any medium line (Im) of the tread band (9) and the rotation axis (X-X) of the vulcanised tyre (2).

Rib- or fin-shaped element (1, 10) comprising an anchoring part (1 b.sub.1, 10b.sub.1) and a molding part (1b.sub.2, 10b.sub.2), wherein the anchoring part (1 b.sub.1, 10b.sub.1) can be anchored in a profile ring segment of a profile ring of a vulcanizing mold that molds the tread of a vehicle tire and the molding part (1 b.sub.2, 10b.sub.2) is provided for molding a sipe or a groove in the tread. The element (1, 10) has at least one elongate projection (1a, 11), which forms a bevel at the periphery of the tread and is produced by means of selective laser melting.

A curing bladder (7) for a tire has a shape exhibiting symmetry of revolution with a central axis and comprises a flexible wall made of cross-linked rubber, the external surface (20) of the wall comprising an air drainage zone (21) and an air removal zone (22) adjacent to the drainage zone, the bladder (7) being equipped with an air drainage structure comprising elements recessed into the external surface, the recessed elements forming a network of channels (30) extending in the air drainage zone (21) and as far as the air removal zone (22). The depth of a channel (30) of the network, defining the shortest path (31) connecting any point of the network of channels, which is situated in the air drainage zone (21), and the air removal zone (22), increases along the length of the path.

A pneumatic tire includes a transponder extending along a circumferential direction embedded between a position (P1) located on an outer side of and 15 mm away from an upper end of a bead core in a radial direction and a position (P2) located on an inner side of and 5 mm away from an end of a belt layer in the radial direction, and a tire inner surface in which a release agent layer made of a release agent is formed has a surface electric resistivity of 10.sup.9 Ω.Math.cm to 10.sup.15 Ω.Math.cm. The transponder extending along the circumferential direction is embedded between the position (P1) and the position (P2), and the amount of silicon of the release agent at least in the tire inner surface corresponding to an embedment section for the transponder is 10.0 wt % or less or a thickness of the release agent is 100 μm or less.

A device and a method for handling tires, as well as a tire curing press including a device of this type. The device for handling tires includes a fork which can be moved under a vulcanized tire in a tire curing press, such that the tire can be taken up by the fork and unloaded from the vulcanization chamber of the tire curing press.

Tires having a magnetic tire sealing material containing magnetic particles are described for detecting the presence of one or more sealed punctures in the tire. The tires can have a sealed tire portion that is formed by the magnetic tire sealing material flowing into and filling a puncture in the tire. The sealed tire portion includes a portion having magnetic particles and the portion being at the outer surface of the tire such as in the tread area. The tire can be positioned within the detection zone of an apparatus capable of detecting magnetic particles to indicate whether the tire contains a sealed puncture filled with the magnetic tire sealing material.

A pneumatic tire is provided with a noise damper made of a sponge material attached to a radially inner surface of the tread portion. The noise damper has protruding portions protruding from a radially inner surface of a band-shaped base portion. The protruding portions extend from one edge to the other edge of the base portion in the widthwise direction, and arranged at intervals in the tire circumferential direction. In a cross section of the tire parallel with the tire equatorial plane, the radially inner surface of each of the protruding portions includes a flat portion, and the radially inner surface of the base portion includes an arc portion parallel with the inner surface of the tread portion.

A tire that includes a decorative pattern formed on a surface of a sidewall portion. The decorative pattern is formed such that a plurality of ridges that extend in a tire radial direction are aligned in a tire circumferential direction so as to form gaps. A transverse cross-section of each ridge is tapered so as to gradually reduce a length along the surface such that the greater a distance from the surface is, the less the length along the surface is. The decorative pattern is structured so as to satisfy expressions (1) and (2):
20≤A≤40  (1)
0.15≤C≤0.25  (2)
wherein A represents a taper angle (degree) of the ridge, and C represents a minimum length (mm) of each gap measured along the surface.
