A pneumatic tire includes a carcass whose cords are coated with coating rubber, at least one of a bead core and a bead filler whose outer surface which faces the carcass is formed from a resin that is harder than the coating rubber, and a buffer layer that is disposed between the coating rubber and the resin, and that reduces shear stress generated in the coating rubber.

A tire includes: a carcass ply, and an inner liner provided to a tire inner cavity side of the carcass ply, in which an electronic component is arranged between the carcass ply and the inner liner. Furthermore, the electronic component may be covered by rubber sheets.

The invention includes methods for forming a retreaded tire and treads there for. Particular embodiments of such methods include providing a tire carcass configured to receive a tire tread along an annular tread-receiving area and a pre-formed tread comprising a tread body and a submerged void arranged along a bottom side of the tread and extending into the tread thickness to a top end located below the top side of the tread, the submerged void having a length and an opening arranged along the bottom side when the tread is in an uninstalled configuration, where the opening of the submerged void extends in a direction of the submerged groove length along an alternating, non-linear path. Further steps include assembling a retreaded tire by arranging the tire tread atop a bonding layer arranged between the tire tread and the tire carcass and comprising uncured bonding material.

A tire 1 for motorcycles comprises a carcass 6, a belt layer 7, and a tread rubber 2G. The belt layer 7 includes at least one reinforcing cord coated with rubber and spirally wound. In a meridian section passing through a tire rotational axis of the tire 1 in a standard state, a width BW of the belt layer 7 in a tire axial direction is in a range of from 60% to 80% of a tread width TW. The tread rubber 2G has a thickness at a tire equator (C) in a range of from 70% to 90% of thickness at tread edges (2t).

Disclosed are a high-performance hybrid tire cord capable of realizing high performance and lightweight of a tire, and a method for manufacturing same. The hybrid tire cord of the present invention comprises a PET primarily-twisted yarn, an aramid primarily-twisted yarn, and an adhesive coated on the PET primarily-twisted yarn and the aramid primarily-twisted yarn. In the hybrid tire cord having a predetermined length, the length of the aramid primarily-twisted yarn is 1 to 1.1 times the length of the PET primarily-twisted yarn, after the secondary twist is untwisted.

A heavy goods vehicle tire has a radial carcass reinforcement, made up of a single layer of metal reinforcing elements anchored in each of the beads by a turn-up around a bead wire. The turn-up of the carcass reinforcement layer and the main part of the carcass reinforcement layer are coupled, and a radiofrequency communication module is placed in the coupling region at the interface between the turn-up of the carcass reinforcement layer and axially outwardly adjacent layer of rubber compound.

A tire is equipped with a radiofrequency communication module with a carcass reinforcement comprising two carcass plies such that the communication module is positioned in the bead axially on the outside of and against the second carcass ply.

A pneumatic tire includes a tread, side walls, beads, a carcass, a belt layer, an inner-liner layer, and a sealant layer. The inner-side surface of the inner-liner layer to which the sealant layer is adhered has profile that satisfies L1<L2<L3, L15 mm, L29.5 mm, and L311 mm, where L1, L2 and L3 represent heights in a radial direction measured from a base height point to the inner-side surface of the inner-liner layer at positions located in an axially inward direction from an axial outer edge of the belt layer by 5%, 10% and 15% of a maximum width of the belt layer, and the base height point is a point on an axial-direction line through the intersection where a radial-direction line passing through the axial outer edge of the belt layer intersects the inner-side surface of the inner-liner layer.
