Abstract: A tire has a tire center in the tire width direction. An intersection point of a carcass outer surface with a parallel line extending parallel with a rotation axis and passing through a tire maximum width position is denoted as P1. An intersection point of the parallel line LP with a side surface is denoted as P2. An intersection point of the parallel line with a protrusion portion outer surface of a protrusion portion is denoted as P3. A distance between the tire center and the intersection point P1 is denoted as W1. A distance between the tire center and the intersection point P3 is denoted as W3. A distance between the intersection point P1 and the intersection point P2 is denoted as G1. A distance between the intersection point P2 and the intersection point P3 is denoted as G2. 0.80≤W1/W3≤0.95 and 0.1≤G1/G2≤1.

Abstract: A tire having a rubber assembly including a first rubber member, a second rubber member, and a third rubber member which are arranged in series in the cross-section including the tire rotational axis. The method includes: extruding the unvulcanized rubber assembly as two separate parts which are a first extrusion rubber portion and a second extrusion rubber portion divided at a division surface passing through the unvulcanized first rubber member; winding the first extrusion rubber portion into a base annular body; and forming the unvulcanized rubber assembly by winding the second extrusion rubber portion so that only the first rubber member included in the second extrusion rubber portion overlaps with the first rubber member included in the base annular body.

Abstract: A pneumatic tire has a non-stretchable tread (30) flanked by two shoulder regions (34), and two non-stretchable bead regions (36) for mounting the tire to a wheel, each bead region being connected via a sidewall to the corresponding bead region. Each sidewall has a first portion (38) extending inwardly relative to a width of the tire from one of the bead regions (36) to a deflection region (40), and a second portion (42) extending outwardly relative to the width of the tire from the deflection region (40) to a corresponding one of the shoulder regions (34). A non-stretchable girth-limiting configuration (44, 46, 56) and a radial reinforcing structure (48, 50, 52) are associated with the first portion (38) of each of the sidewalls, thereby limiting radial flexing of first portion (38) and maintaining an annular concavity between the bead region (36) and the shoulder region (34).

Abstract: A pneumatic vehicle tire of a radial type of construction with a profiled tread (1), sidewalls (3), bead regions (2) and an airtight inner layer (4), which forms the inner side (4a) facing the interior space of the pneumatic vehicle tire, ribs (6) being formed on the inner layer (4), having been imprinted in it by a heating bladder introduced into the interior of the tire during the vulcanizing of the pneumatic vehicle tire in a tire heating mold, and a sound absorber (5) being provided so as to extend in an annular manner on a circumferential region (4b) of the inner side (4a) opposite from the tread (1).
Grooves (7) have been formed by the heating bladder at least in a partial region of the circumferential region (4b) of the inner layer (4a) on which the sound absorber (5) is provided.-

Abstract: A pneumatic tire includes, on a surface of a side rubber provided on sidewall portions, a two-dimensional code in which a dot pattern is formed by two types of gray scale elements distinguishable from each other by irregularities on the surface. Dot holes are formed in the two-dimensional code, corresponding to dark elements of the gray scale elements. The side rubber is a diene rubber including butadiene rubber, and when A is a blended amount of the butadiene rubber relative to 100 parts by mass of the diene rubber contained in the side rubber and when B is a blended amount of carbon, a ratio A/B and a hole depth D (mm) from an opening of the dot hole to a hole bottom satisfies a relationship of 1.1≤(A/B)/D≤6.0.

Abstract: A heavy-duty pneumatic tire includes a section width being equal to or less than 335 mm, an aspect ratio being equal to or less than 55%, and a toroidal carcass extending between axially spaced bead portions through a tread portion and sidewall portions. The carcass includes a carcass ply which includes a main portion and a turn-up portion turned up around a bead core of each bead portion. A belt layer is disposed radially outward of the carcass in the tread portion, wherein a radially outer end of the turn-up portion is located between the main portion and the belt layer in the tread portion. A sheeted rubber layer is disposed between the main portion and the turn-up portions in each sidewall portion.

Abstract: The invention relates to a polymer product, preferably a vehicle tire (1) with sidewalls (2), comprising a photorealistic representation (3) on the outer surface of the polymer product (2), wherein the photorealistic representation consists of the combination of a structure with a relief (5) of the representation, wherein the structure has elevations (7) and depressions (6) and wherein the relief (5) is a depth chart of the representation that is preferably produced on the basis of grayscale values of a photo and has up to 256 gradations of depth in such a way that the relief (5) fills the depressions (6) of the structure to different heights according to the grayscale value.
For generation of a photorealistic representation (3), the structure is an undirected texture (4) composed of elevations (7) and depressions (6).
