TIRE
A tire including a bead core; bead filler; upper ply; reinforcement ply which is provided to overlap a tire-radial direction inside portion of the upper ply; and down ply which overlaps a turnup part of the upper ply and reinforcement ply, and extends from an outer side in the tire-radial direction to an inner side in the tire-radial direction so as to encompass the bead core and bead filler together with the upper ply, in which an electronic component is embedded in a region of substantially triangular shape in a cross section surrounded by the turnup part of the upper ply, down ply and an end part of the reinforcement ply.
Pneumatic Tire
A pneumatic tire includes a tread portion; sidewall portions disposed on both sides of the tread portion; a pair of bead portions positioned inward of each of the sidewall portions in a tire radial direction; at least one layer of carcass spanning between the pair of bead portions; and an organic fiber reinforcement layer that is provided to at least one of the sidewall portions and is made of an organic fiber material are provided. The organic fiber reinforcement layer is provided closer to a tire outer surface than the carcass at a position within a range from 50% or greater to 90% or less of a tire cross-sectional height toward an outer side in a tire radial direction from an inner end portion of the bead portion in a tire radial direction.
TIRE
A tire includes a bead core; a bead filler which extends to an outer side in a tire-radial direction of the bead core; a carcass ply which extends from the bead core to another bead core and is folded around the bead core; a rim strip rubber which is arranged at least at an outer side in a tire-width direction of the carcass ply which has been folded back around the bead core; and a side-wall rubber covering a part on an outer side in the tire-width direction of the rim strip rubber, in which an RFID tag serving as an electronic component is provided between the rim strip rubber and the side-wall rubber.
Heavy duty tire
A heavy-duty tire is described herein. The heavy duty tire includes a carcass, a tread located radially outward of the carcass, and a tread having a plurality of lugs. The lugs extend radially outward from an inner tread and are located between the first and second lateral tread edges. The tread further includes a first row of lugs extending from the tread lateral edge axially inwards toward the centerplane, and a second row of lugs extending from the opposite tread lateral edge and axially inwards toward the centerplane. The lugs of the first and second rows are separated by a plurality of shoulder grooves, wherein the first row of lugs are aligned with the second row of lugs, a center row of lugs located between a first and second offset lug, wherein all of the lugs in each row are aligned circumferentially. wherein said tire has a molded base width in the range of 44-50 mm. The heavy-duty tire wherein the shoulder drop ranges from 64 mm to 120. Wherein the gauge of the shoulder wedge ranges from 70-89 mm, and more preferably in the range of 75-85 mm.
PNEUMATIC TIRE WITH REINFORCEMENT MATERIAL
A pneumatic tire with a reinforcement material includes: a tread that comes in contact with a road surface; side walls that extend and form shoulders and inner liners at both sides of the tread; a carcass that is integrally attached to the tread and the inner sides of the side walls and forms a turn-up head at both ends of the side walls; a belt layer that is layered on the tread of the carcass; and a bead that includes a bead core inserted in a wheel inside the turn-up head, a bead filler inserted in a side of the tread of the bead core, and a reinforcement material inserted in an interface of the turn-up head.
Heavy-duty tire
A heavy-duty tire includes a tread part formed such that the tread part includes a crown profile including tire equator, and a pair of shoulder profiles extending from outer sides of the crown profile to tread edges. In a tire cross section including tire rotation axis in 5% internal pressure state in which the tire is mounted to a normal rim, filled with air at internal pressure of 5% of normal internal pressure and loaded with no load, each of the crown and shoulder profiles has an arc shape convex toward tire radial direction outer side such that ratio Rc/Rs of curvature radius Re of the crown profile to curvature radius Rs of each shoulder profile is 7.0 or more, and a tire axial direction distance from the equator to a connecting point between the crown profile and each shoulder profile is 0.70 or more times a tread half width.
BEAD MEMBER FOR TIRE, TIRE, AND METHOD OF PRODUCING BEAD MEMBER FOR TIRE
A bead member for a tire, including: a bead wire; a first bead filler that is in contact with the bead wire directly or via another layer and is arranged in a region including at least a region at an outer side of the bead wire in a tire radial direction; and a second bead filler that is in contact with the first bead filler directly or via another layer and is arranged in a region including at least a region at an outer side of the first bead filler in the tire radial direction, the first bead filler including a resin A, the second bead filler including a resin B, and the resin B having a melting point higher than that of the resin A.
TIRE HAVING A REINFORCED LOWER ZONE
A tire for a motor vehicle comprising: two beads (20); two sidewalls (30) meeting at a crown (25); at least one carcass reinforcement (160) extending from the beads (20) through the sidewalls (30) as far as the crown (25), the carcass reinforcement (160) having a plurality of carcass reinforcing elements and anchored in the two beads (20) by a turn-up around the annular reinforcing structure (70), so as to form in each bead a main strand (162) and a turn-up strand (163); and a stiffening reinforcement (140) arranged in at least one sidewall of the tire, said stiffening reinforcement (140) having a radially inner end (141) and a radially outer end (142), the stiffening reinforcement being formed of a plurality of stiffening elements oriented at an angle less than or equal to 10 relative to a circumferential direction of the tire.
PNEUMATIC TIRE
A pneumatic tire includes bead cores, a carcass ply and a belt. The carcass ply includes: a first ply having a central portion positioned inward of the belt in the tire radial direction, a pair of side portions extending inward from opposite ends of the central portion in the tire radial direction, and folded-up portions extending from the respective side portions, being folded up around the respective bead cores; and a second ply being discontinuous and disposed outward of the first ply in the tire radial direction, having a pair of ply pieces provided with inner ends positioned on respective sides of the central portion of the first ply, side portions extending inward from the respective inner ends in the tire radial direction, and folded-up portions extending from the respective side portions, being folded up around the respective bead cores. The first ply has a ply-overlapping portion.
PNEUMATIC TIRE AND MOLD FOR VULCANIZATION-MOLDING SAME
A pneumatic tire has a turned-up carcass ply and a non-turnup carcass ply. The turned-up carcass ply is turned up around bead cores in respective bead portions from the inside to outside of the tire so as to form a pair of turned up portions extending radially outwardly on the axially outsides of the respective bead cores, and a main portion extending between the turned up portions. The non-turnup carcass ply extends between the bead portions and terminates to have edges positioned on the axially outsides of the respective turned up portions. The bead portions are each provided on its outer surface with vent lines protruding therefrom and extending continuously in the tire circumferential direction. The vent lines include a radially outer vent line formed radially outside the edges of the non-turnup carcass ply, and a radially inner vent line formed radially inside the edges of the non-turnup carcass ply.
