Provided is a pneumatic tire. A band-like sound absorptive member is fixed to the inner surface of a tread portion along the tire circumferential direction. An end portion in the tire width direction of the sound absorptive member is located on the outer side in the tire width direction with respect to a shoulder main groove located on the outermost side in the tire width direction. A width W1 of the sound absorptive member in the tire width direction and a tread development width TDW of the tread portion satisfy a relationship of 0.65≤(W1/TDW)≤0.90. The width W1 of the sound absorptive member and a belt width W2 of a first belt ply having the maximum width of a belt layer satisfy a relationship of 0.70≤(W1/W2)≤0.95.

A tire comprises an interior surface and an exterior surface, an accommodating region arranged on one of said interior and exterior surfaces, an adhesive layer arranged on the accommodating region and a member attached to the accommodating region by the adhesive layer, in which the adhesive layer is based on a silanized polyether.

Apparatus for applying noise-reducing elements to a tyre for vehicle wheels that has a radially inner surface with a service area and a circumferential dimension. The apparatus determines the position in circumferential direction of the service area, determines the position in circumferential direction of a target area on the radially inner surface of the tyre based on the position in circumferential direction of the service area, and applies a noise-reducing element the target area. The position in circumferential direction of the service area is determined by circumferentially inspecting the radially inner surface of the tyre starting from a reference position, detecting the angular position of the service area with respect to the reference position and determining the position in circumferential direction of the service area based on the angular position and on the circumferential dimension of the radially inner surface of the tyre.

A tire fitted with a transponder comprises: a crown comprising a crown reinforcement having an axial end at each of its edges, connected at each of its axial ends by a sidewall to a bead having an interior end; a carcass reinforcement layer formed of parallel reinforcers, which is anchored in each bead around a bead wire to form a main part and a turn-up; the transponder comprising a core defining a first axis, a first cover filament helically twisted around the core and an electrical insulation device; and the first cover filament comprising at least two conductive filamentary elements galvanically connected to an electronic chip comprising a radiofrequency transmission-reception component. The thickness of elastomeric compound separating the outer cover filament, located radially outermost with respect to the first axis, and the reinforcements is greater than 0.5 millimeters.

A disclosed vehicle component may include at least one split-ring resonator, which may be embedded within a material. The split ring resonator may be formed from a three-dimensional (3D) monolithic carbonaceous growth and may detect an electromagnetic ping emitted from a user device. The split ring resonator may generate an electromagnetic return signal in response to the electromagnetic ping. The electromagnetic return signal may indicate a state of the material in a position proximate to a respective split ring resonator. In some aspects, the split-ring resonator may resonate at a first frequency in response to the electromagnetic ping when the material is in a first state, and may resonate at a second frequency in response to the electromagnetic ping when the material is in a second state. A resonant frequency of the 3D monolithic carbonaceous growth may be based on physical characteristics of the material.
