摘要： A tire with improved handling having a stiffening structure with a stiffening element extending continuously in the toroidal interior cavity from a crown interface connected to a radially inner face of the crown to a bead interface connected to an axially inner face of the bead. The stiffening structure is distributed circumferentially over the circumference of the tire, the axially outermost stiffening element interface is positioned, with respect to the equatorial plane (XZ), at an axial distance A at most equal to 0.45 times the axial width S, and the radially outermost stiffening element bead interface is positioned, with respect to a radially innermost point (I) of the axially inner face of the bead at a radial distance B at most equal to 0.5 times the radial height H.

摘要： A tire breaker belt comprises a core ply preferably comprising rubberized cords extending longitudinally of the belt. One or more encasing plies are wrapped around the core ply. The cords of the encasing ply or plies extend at an acute angle to the length of the belt.The belt may be formed directly as an annulus or in a long length which is cut to a shorter length and subsequently wrapped around a carcass.

摘要： A tire assembly according to the disclosure may include a wheel having a first outer circumferential surface and a second outer circumferential surface, and a tire mounted on the wheel and having a first portion that mates with the first outer circumferential surface of the wheel, and a second portion that is spaced away from the second outer circumferential surface of the wheel to form a cavity. Furthermore, the first portion may be a solid portion that extends from the first outer circumferential surface of the wheel to an outer circumferential surface of the tire.

摘要： Provided is a pneumatic tire. Both terminals of a carcass layer are overlapped with each other in a tread region. The carcass layer has a triple layer structure including an inner layer positioned most inward in a tire radial direction in the tread region, an outer layer positioned most outward in the tire radial direction in the tread region, and an intermediate layer positioned between the inner layer and the outer layer in the tread region. A cord angle in the carcass layer in a tread central region with respect to a tire circumferential direction differs in at least one of the inner layer, the outer layer, and the intermediate layer from a cord angle in the carcass layer in a side region with respect to the tire circumferential direction.

摘要： Provided is a pneumatic tire. One terminal of a carcass layer extends to a ground contact edge of a tread portion positioned on an opposite side with respect to a tire center line as a reference. The carcass layer has a double layer structure including an inner layer positioned inward in a tire radial direction in a tread region and an outer layer positioned outward in the tire radial direction of the inner layer in the tread region. A cord angle in the carcass layer in a tread central region with respect to a tire circumferential direction is different from a cord angle in at least one of the inner layer and the outer layer of the carcass layer in a side region with respect to the tire circumferential direction.

摘要： A high aspect ratio agricultural pneumatic tire has a carcass including a pair of bead portions each having a bead core and two pair of first and second carcass plies of synthetic cords oriented radially and wrapped from the inside of each bead core around to an axially outer turnup end. The first pair of plies is radially inward and adjacent the second pair of plies between the bead cores and having the turnup ends T1, T1′ wrapped about the bead cores and the turnup ends T2, T2′ of the second pair of plies. The turnup end of the first pair of plies extends outwardly and radially along the bead filler wherein T1, T1′ are located between 60% and 80% of the radial location Y of maximum section width (SW) of the tire and T2, T2′ are located between 30% and 50% of Y.
