A tire (10, 10) for rotation about an axis of rotation (12) has a first wall portion (14) having a partially conical form, and a second wall portion (16) integrally formed and interconnected with the first wall portion at a transition region (18) so as to define an annular recess. A closure-limiting configuration includes a number of tubular reinforcing elements (20) arrayed around the annular recess. Each tubular reinforcing element has a wall with a closed cross-section. The tubular reinforcing elements (20) are spaced around the annular recess such that deformation of a compressed region of the tire under a load causes a change in shape of the tubular reinforcing elements in the compressed region.

Tire (10) comprises a knit (44) comprising: columns of loops, the loops of one and the same column being arranged one after the other substantially in an overall direction referred to as the main direction and rows of said loops, the loops of one and the same row being arranged one beside the other substantially in an overall direction referred to as the transverse direction. The knit (44) comprises first and second zones (45.sub.1, 45.sub.2), each respectively having, at least in one of the main or transverse directions, a force FT.sub.100 and FS.sub.100 at 100% elongation that satisfies FS.sub.100<FT.sub.100, each force FT.sub.100 and FS.sub.100 being determined from a force-elongation curve obtained by applying standard ISO 13934-1:2013 to the knit before it is incorporated into the tire (10).

A pneumatic tire comprises at least one sidewall portion provided with a serration pattern on its outer surface, the serration pattern comprising a plurality of first groups being repeatedly arranged in the circumferential direction of the tire, each first group comprising a plurality of ridges which are arranged using gradually increasing pitches toward a first circumferential direction of the tire, wherein a region provided with the serration pattern on the outer surface of the sidewall portion has a radius of curvature in a range of not more than 70 mm in a cross section including a tire axis under a standard condition such that the tire is mounted on a standard rim and inflated to a standard pressure, but no tire load is loaded.

In one aspect, a tire assembly is provided, the tire assembly comprising: a tire having a tread, two shoulders, two sidewalls, and two bead portions, wherein the sidewalls are oriented radially between the respective shoulders and the respective bead portions, wherein each of the sidewalls are cantilevered in shape, with each respective shoulder projecting axially outward from the entirety of its respective sidewall, a flexible sidewall support structure oriented axially outward of and in contact with each sidewall and its respective bead portion, wherein the flexible sidewall support structure has an annular shape, wherein the flexible sidewall support structure is external to and separate from the tire, and a flexible panel oriented axially outward of an in contact with each of the tire and the flexible sidewall support structure in the region of each shoulder.

A motorcycle tire includes an insulation rubber layer disposed between a main body portion of a carcass ply and an inner liner layer in each axial half of the motorcycle tire. The insulation rubber layer extends from a first end on a tread portion side at least to a bead core. A sidewall portion includes an outermost end in the tire radial direction of an area of a tire outer surface of the sidewall portion contacting a standard rim. The tire outer surface has a side profile occupying 90% or more of a length in the tire radial direction between the tread edge and the outermost end from the tread edge. The side profile is a linear line or an arc concave axially inward and having a radius of curvature of 55 mm or more.

A tire has, in a cross-sectional view in a tire meridian direction when the tire is mounted on a specified rim, inflated to 230 kPa, and in an unloaded state, a radial distance D3 from a point P1 to a point T3 with respect to a radial distance D1 from the point P1 to a point T1 in a range 0.05D3/D10.15. The tire has a radial distance D6 from the point P1 to a point T6 with respect to the radial distance D3 from the point P1 to the point T3 in a range 3.00D6/D36.00. The tire has a radius of curvature R1 of a first arc passing through the point T3 and points T4 and T5 with respect to a radius of curvature R2 of a second arc passing through the points T1 and T6 and a point T7 in a range 0.40R1/R21.00.

Provided is a pneumatic radial tire for passenger vehicles in which the cross-sectional width SW of the tire and the outer diameter OD of the tire satisfy a predetermined relationship, and an end of the carcass (an end of a carcass turn-up portion when the carcass has the carcass turn-up portion) in one tire width-direction half that is on the inner side when the tire is mounted on a vehicle is located on the inner side in the tire radial direction than an end of the carcass turn-up portion in the other tire width-direction half that is on the outer side when the tire is mounted on a vehicle.

In a tire, a point (Au) on a side profile at the same position in a radial direction as an end portion of an innermost layer of a belt layer is defined in a cross-sectional view in a meridian direction. A distance (Hu) from a maximum width position (Ac) to the point (Au) in the radial direction is defined. A point (Au) on the side profile at the radial position of 70% of the distance (Hu) from the maximum width position is defined. A point (An) on the side profile at the radial position of 35% of the distance (Hu) from the maximum width position is defined. A radius of curvature (RP) (mm) of an arc passing through the maximum width position, the point (Au), and the point (An) with respect to a cross-sectional height (SH) (mm) is in a range 0.20RP/SH1.80.

A tire (1), intended in particular for a private passenger vehicle and comprising at least one sidewall (3) with a protuberance of the sidewall (3) close to the connection of the tire with its mounting rim (2), and intended to reduce the aerodynamic drag and hence the resistance to forward motion of the wheel, in order to contribute to the reduction in fuel consumption and hence to the reduction in CO2 emissions. According to the invention, when the tire (1) is mounted on the rim (2) and inflated to a pressure as defined by the ETRTO standard, the radially inner end I of the protuberance (6) is positioned radially inside the radially outermost point J of the rim flange (21) at a radial distance H1 at most equal to 10 mm, or radially outside the radially outermost point J of the rim flange (21) at a radial distance H1 at most equal to 4 mm.
