A composite tire, having an outer tube and an inner tube made of different materials or the same material but in different densities; an inner circumferential surface of the outer tube is integrally formed with protruding rings; projections or slots are provided on each of the protruding rings; the inner tube is integrated to the inner circumferential surface of the outer tube; the inner tube is divided into different layers made of different materials or the same material but in different densities; the inner tube engages with the protruding rings such that if the projections are provided on each of the protruding rings, the projections are wrapped by the inner tube, or if the slots are provided on each of the protruding rings, the slots are filled by the inner tube. The composite tire is resistant to wearing and also comfortable to use.

The invention relates to a hybrid cord for use as a reinforcement in a belt bandage of a pneumatic vehicle tire, consisting of at least two threads with ends which are twisted together. At least one first thread is a high-modulus thread with a specified thread fineness, and another thread is a low-modulus thread, said other low-modulus thread having a lower thread fineness than the first thread. The invention is characterized in that the proportion of the high-modulus thread in the hybrid cord is 80-95 wt. %; the difference between the thread fineness of the high-modulus thread and the thread fineness of the other low-modulus thread is >800 dtex; and the elongation at break of the high-modulus thread ranges from 1%-8%, and the elongation at break of the low-modulus thread ranges from 9%-30%.

A pneumatic radial tire includes a carcass structure having a pair of sidewalls and a crown, a pair of beads, a tread, a belt structure, and a plurality of reinforcing hoops. The plurality of spaced apart reinforcing hoops are disposed intermediate the crown of the carcass structure and the tread, and are formed of a rigid material coated in an elastomeric material. The plurality of reinforcing hoops includes a pair of outer reinforcing hoops disposed adjacent the sidewalls of the carcass, and an at least one inner reinforcing hoop disposed between the outer reinforcing hoops.

The invention relates to a reinforcement cord for elastomeric products, in particular for pneumatic tires, comprising at least one yarn made of filaments.

The invention further relates to an elastomeric product comprising at least one reinforcement cord.

For protection of the environment and conservation of resources, together with good processing performance, at least one yarn of the reinforcement cord comprises filaments made of polybutylene dicarboxyfuranoate (PBF), where the PBF has been produced entirely or at least to some extent from biomass and/or from renewable raw materials.

A reinforcement structure for a polymer ply includes a plurality of flat woven cords. Each flat woven cord has a width between 0.5 mm and 1.6 mm and a thickness between 0.2 mm and 0.8 mm thereby producing the reinforcement structure with an overall width between 25.0 mm and 26.0 mm. Each flat woven cord includes materials with melting points between 130° C. and 230° C.

A pneumatic tire includes a pair of bead portions each having a respective bead core therein, a carcass extending between the bead portions and including a carcass ply that includes a main portion extending between the bead cores and a pair of turn-up portions turned up around the bead cores, and a pair of bead reinforcing layers being disposed outward in the tire axial direction of the turn-up portions so as to cover outermost ends in a tire radial direction of the turn-up portions. An outer surface of at least one of the bead portions is provided with a recess row including a plurality of recesses spaced in a tire circumferential direction, and in the at least one of the bead portions, an outermost end of the bead reinforcing layer is located outwardly in the tire radial direction of outermost ends of the plurality of recesses.

Motorcycles tyre including a carcass structure, a zero-degree belt structure arranged in a radially outer position with respect to the carcass structure and a tread band arranged in a radially outer position with respect to the belt structure. The belt structure includes at least one hybrid reinforcing cord that has an elongation greater than 4% when subjected to a load equal to about 50 N and a tangent modulus with a monotonic progression as the elongation increases for elongations comprised between 4% and at least 9%.

A tire includes a spiral belt layer and ring-shaped bands. The spiral belt layer is provided at the outer periphery side of a tire carcass member and is formed by a resin-coated cord wound in a helical shape. The bands are disposed at the tire diameter direction outer side of each of an end portion of the spiral belt layer at one side in the tire width direction and an end portion at the other side. Each band includes a belt-shaped member that is wound at least one full circumference in the tire circumference direction. The band is provided with an overlap portion that is specified with a larger number of layers of the belt-shaped member than other regions of the band in the circumference direction. The overlap portion is disposed at a circumference direction position that does not correspond with length direction end portions of the resin-coated cord.

High performance textile cords having residual twist in ply-yarns in cord are used as reinforcement in bias and radial pneumatic tires. The high performance textile cords have a residual ply-yarn twist multiplier, wherein the residual ply-yarn twist multiplier is greater than 1,000 and less than 4,000 and a residual twist direction of a plurality of ply-yarns in Z or S direction is in an opposite direction of a cord twist, in S or Z direction.

A method for backing up a trailer hitched to a vehicle includes mounting a rear backup camera at a vehicle and hitching a trailer at the hitch of the vehicle. Responsive to processing captured image data by a processor of the control, at least a portion of the trailer tongue of the trailer is detected using an edge detection algorithm. Responsive to processing at the control of image data captured by the rear backup camera during a backing up maneuver of the trailer hitched to the vehicle, trailer angle of the trailer relative to a longitudinal axis of the vehicle is determined. The control, based at least in part on trailer angle of the trailer, controls a steering system of the vehicle during the backing up maneuver of the trailer hitched to the vehicle to back up the trailer hitched to the vehicle along a rearward trajectory.
