In a first aspect of the invention, a pneumatic tire is provided, the pneumatic tire comprising two spaced apart beads, a tread portion, a pair of sidewalls extending radially inward from axially outer edges of the tread portion to join the respective beads, the axially outer edges of the tread portion defining a tread width, a carcass, an innerliner covering the carcass and enclosing a tire cavity when mounted on a rim, and multiple layers of open cell, noise damping foam strip material attached on top of each other to the innerliner within the tire cavity in an area radially below the tread portion, wherein each layer has an axial width from 20% to 80% of the tread width and a radial thickness from 5% to 20% of the tread width and said multiple layers fill together from 8% to 40% of the volume of the tire cavity.

Pneumatic tire

In a first aspect of the invention, a pneumatic tire is provided, the tire comprising two spaced apart bead portions, a tread portion, a pair of sidewalls extending radially inward from axially outer edges of the tread portion to join the respective bead portions, the axially outer edges of the tread portion defining a tread width, a carcass, an innerliner covering the carcass and defining a tire cavity, and a metal coated foam material attached to the innerliner within the tire cavity.

In a first aspect of the invention, the invention is directed to a pneumatic tire comprising two spaced apart bead portions, a tread portion, a pair of sidewalls extending radially inward from axially outer edges of the tread portion to join the respective bead portions, the axially outer edges of the tread portion defining a tread width, a carcass, an innerliner covering the carcass and defining a tire cavity, and multiple layers of foam strip material attached on top of each other to the innerliner within the tire cavity in an area radially below the tread portion, wherein at least two of the layers are interlocked to each other along their length so as to hold the layers together in a radial direction.

Tire

The present invention is directed to a pneumatic tirecomprising at least one pair of parallel annular beads; at least one carcass plywrapped around said beads; a tread; and first and second sidewalls disposed between said tread and one of said at least one pair of beads; as well as a belt portionbetween the carcass plyand the tread. In accordance with the invention, the treadcomprises a tread base layerand a plurality of tread blocks, wherein the tread blockscomprise at least two different rubber layersarranged radially above each other, whereas the rubber layersof different tread blocks are axially separate from each other.

A pneumatic radial tire has a pair of opposing bead portions, each bead portionhas a bead coreand a bead apex; at least one carcass reinforcing plyhaving radially oriented steel cords, the at least one carcass reinforcing plyhas a main portionand two turnups, one turnupextending from each end of the main portionand having a terminal end, the carcass reinforcing ply main portionextends between the opposing bead coresand turnupsare located axially outward of the bead coreand a portion of the bead apex; and two pairs of steel cord reinforced chippers, one pair adjacent each turnup, each pair having one inner chipperbeing adjacent and on an axially inner side of the turnupand one outer chipperbeing adjacent on an axially outer side of the turnup, the inner and outer chippersbeing adjacent the turnupeach have a terminal endextending radially outward of the terminal endof the turnup

A tire treadfor a vehicle tire has a plurality of tread elementsextending radially outwardly from a tread baseto a radially outer surface. Each tread elementis defined by adjacent grooves. The treadhas at least one tread elementprojecting from the tread baseand having one or more tread wear indicators TWI. Each TWIis located at the intersection of two groovesadjacent or integral to the at least one tread element

A pneumatic tire includes a carcass ply extending from one bead structure to another bead structure. Each bead structure includes a plurality of circumferentially wound metal wires defining a cross-sectional profile of a bead. The profile has a radial height to axial width ratio greater than 1.0 and a bead orientation angle between 30 degrees and 60 degrees.
