Provided is a pneumatic tire ensuring conductivity while being reduced in weight, and having good fuel efficiency and handling stability. The tire includes a sidewall and a carcass, the sidewall including a laminate of two or more rubber layers including an inner sidewall layer (1) located closest to the carcass, and an outer sidewall layer (2) constituting an outer surface of the tire; the layer (1) including a rubber composition for (1); the layer (2) including a rubber composition for (2); the carcass including a carcass cord topped with a rubber composition for a carcass cord topping (3); the sidewall having a thickness of 3.0 mm or less; the layer (1) having a thickness of 0.2-1.0 mm; the composition for (1) having a volume resistivity of 5.010.sup.7 .Math.cm or less; the compositions for (1) and for (2), and the compositions for (3) and for (1) satisfying specific relations.

A tire includes a first side and a second side, and a tread portion extending between the first side and the second side. The first side includes external geometry having at least one rib surrounding a recess, without extending into the recess. The recess is configured to receive a tire electronic device.

The present invention is directed to a tire comprising a tread, at least one carcass ply, a pair of bead portions, a pair of sidewalls, wherein each sidewall of the pair of sidewalls extends between the tread and a respective bead portion of the pair of bead portions. At least one sidewall of the pair of sidewalls comprises a first circumferential sidewall layer and a second circumferential sidewall layer extending along an axially inner side of the first sidewall layer, between the first sidewall layer and an adjacent carcass ply.

A process for producing a vulcanizable composite material, including the steps of: a) producing or providing a textile strength member, b) treating the textile strength member with an aqueous dispersion for adhesive activation of the textile strength member and to obtain an adhesion-activated textile strength member and c) introducing the adhesion-activated textile strength member into a crosslinkable rubberization mixture to obtain the vulcanizable composite material, wherein the aqueous dispersion is essentially free of free resorcinol and resorcinol precondensates, especially resorcinol-formaldehyde precondensates, and is free of free formaldehyde and formaldehyde-releasing substances, wherein the crosslinkable rubberization mixture is processible by vulcanization to give a crosslinked rubberization mixture which is at least partly transmissive to visible light at least in sections.

A tire (1) having at least one sidewall (3), intended to interact with a sidewall insert (9) by way of an anchor (6), and aims to personalize the design of the sidewall. The anchor (6), has a recess (7) formed in an axially outer sidewall layer (30), with a protuberance (8), which is raised in relation to the recess bottom (71) and extends from the recess bottom (71) to the vicinity of the axially outer sidewall face (31), and the protuberance (8) is constituted by a stepped arrangement of a first narrow portion (81) having a minimum width Lpmin and a second wide portion (82) having a maximum width Lpmax, such that the difference LpmaxLpmin is at least equal to 1 mm and at most equal to 4 mm.

A tire includes an annular decoration printing portion, at least a portion thereof being provided on an outer surface of a side portion further toward a tire radial direction outer side than a tire maximum width position. The decoration printing portion includes an annular design portion and an annular gradation portion provided at least on the tire radial direction outer side of the design portion. The gradation portion incrementally decreases in value outward in the tire radial direction, with a value of 100% being a pure color and a value of 0% being pure black in an HSV color space.
