A tire includes a carcass, a tread disposed radially outward of the carcass, a sidewall including a shoulder extends toward the tread, and a reinforcing structure positioned radially between the carcass and the tread. The reinforcing structure includes a plurality of belts extending axially toward the shoulder and an overlapping spiral wound strip positioned at a radially outermost portion of the reinforcing structure. The overlapping spiral wound strip includes a uniform width having groups of four first cords with a single second cord therebetween. The first cords include a hybrid construction and the second cords include a single material construction.

A tire for an agricultural vehicle (1), and in particular the carcass reinforcement (4) thereof, for a tire running at low pressure on loose ground, is to reduce the compaction of the ground and to increase the traction capability by reducing the structural stiffness of the tire. According to the invention, the carcass reinforcement (4) is made up of a single carcass layer (41) having a mean thickness E at most equal to 2 mm and a breaking strength Fr, expressed in daN/cm, that satisfies the relationship:

Fr>=Fs=(Cs*Pmax*10.sup.−3)*((R.sup.2−((R+Rj)/2).sup.2)/2)/Rj, with Fs: reference threshold strength (in daN/cm) Cs: safety factor at least equal to 1, Pmax: recommended maximum inflation pressure (in kPa), R=D/2: outside radius of the tire (in mm), Rj=Dj/2: nominal radius of the rim (in mm).

The present invention relates to a vehicle tire comprising a belt bandage, wherein the belt bandage comprises strength members, wherein the strength members comprise hybrid cords arranged parallel to one another within the ply, and wherein the hybrid cords each contain at least one yarn made of polyethylene terephthalate (PET) and at least one yarn made of polyamide.

According to the invention the PET of the yarn of the hybrid cord of the belt bandage is recycled PET (rPET).

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 tire comprises a crown reinforcement comprising: a working reinforcement comprising a single working layer and a hoop reinforcement arranged radially outside the working reinforcement and comprising at least one hooping filamentary reinforcing element (170) wound circumferentially helically so as to extend axially from one axial edge to the other axial edge of the hoop reinforcement. The or each hooping filamentary reinforcing element (170) consists of: two multifilament strands (1701, 1702) of aromatic polyamide or aromatic copolyamide and one multifilament strand (1703) of aliphatic polyamide or of polyester, or three polyester multifilament strands, each multifilament strand (1701, 1702, 1703) being wound in a helix around a main axis (W) common to the three multifilament strands (1701, 1702, 1703). The hoop reinforcement has a tangent modulus at 1.3% elongation ranging from 200 to 650 daN/mm.

A tire includes a tread, a crown reinforcement, a carcass reinforcement with at least one ply wound about a pair of bead cores and through two sidewalls of the tire, and a cut/puncture resistant sidewall layer disposed adjacent a part of the carcass reinforcement within one of the sidewalls, the cut/puncture sidewall layer being formed of a plurality of cords, each cord including one nylon cord having S 4-8 tpi (twists per inch), one aramid cord having Z 4-8 tpi, and the nylon cord and the aramid cord being twisted together with S 3-7 tpi.

A composition of epoxide-functionalized resins comprises at least a first epoxide-functionalized novolac resin, a second epoxide-functionalized novolac resin, and a curing agent selected from phenolic or amine-type curing agents, the average molar mass of the group consisting of the entirety of the epoxidized novolac resins in the said composition being between 550 and 650 g/mol, the average epoxide functionality of the said group being between 3 and 3.5 eq epoxide/mol, and the said composition having a glass transition temperature Tg of at least 160° C.

A pneumatic tire, wherein, in a state of being mounted on a rim, defining the rim diameter as D, the length from the rim position representing the rim diameter D to the maximum tire radial height as SH, the rim flange height as G, the rim flange radius as R.sub.2, and the bead filler height H.sub.bf as the tire radial height with respect to the rim position representing the rim diameter D, the bead filler height H.sub.bf is less than or equal to a value obtained by the following formula: {SH−(G−R.sub.2)}/4+(G−R.sub.2). The cord is provided in at least one part from a bead portion to a sidewall portion 3 at an angle of 0 to 10° to the circumferential direction.

An imaging system for a vehicle includes an imaging sensor and a video display device. The imaging system generates an overlay that is electronically superimposed on the displayed images to assist a driver of the vehicle when executing a backup maneuver. The overlay has first, second and third overlay zones, with the overlay zones indicative of respective distance ranges from the rear of the vehicle to respective distances. As indicated to the driver viewing the video display screen when executing a backup maneuver, the first distance is closer to the rear of the vehicle than the second distance and the second distance is closer to the rear of the vehicle than the third distance. The first overlay zone may be a first color and the second overlay zone may be a second color and the third overlay zone may be a third color.

Disclosed are a hybrid fiber cord comprising a nylon filament and an aramid filament, the cord having more uniform physical properties and better strength and fatigue properties and being able to be made more easily than the conventional hybrid fiber cords such that it can be used to make an ultra high performance tire, and a method for manufacturing the same. The hybrid fiber cord comprises a nylon primarily-twisted yarn having a first twist number, and an aramid primarily-twisted yarn having a second twist number. The first twist number is identical with the second twist number. The nylon and aramid primarily-twisted yarns are secondarily-twisted together to have identical structures with each other.
