The tire includes: a tire frame member which is made of resin and includes: a bead portion covering a bead core; a side portion extending outwardly in a tire radial direction from the bead portion; and a crown portion extending inwardly in a tire width direction from the side portion, and the tire also includes a reinforcing layer which includes plural cords covered by resin or rubber and which extends from the bead portion to the side portion of the tire frame member to cover at least an inner peripheral surface of the side portion.
TIRE FOR TWO-WHEELED AUTOMOTIVE VEHICLE
[Object] A tire, for a two-wheeled automotive vehicle, which is excellent in ride comfort and steering stability, is provided.
[Solution] A tire 12 for a two-wheeled automotive vehicle includes a carcass 20 that is extended on and between one of beads 18 and the other of the beads 18 along inner sides of a tread 14 and sidewalls 16. The carcass 20 includes a first ply 34 and a second ply 36 that is layered outward of the first ply 34. The first ply 34 is turned up around the beads 18 from an inner side toward an outer side in an axial direction. By the turning-up, the first ply 34 includes a main portion 34a and turned-up portions 34b. The second ply 36 is turned back around the beads 18 from the outer side toward the inner side in the axial direction. By the turning-back, the second ply 36 includes a main portion 36a and turned-back portions 36b.
Tire provided with a radio frequency communication module
A tire is equipped with a radiofrequency communication module with a carcass reinforcement comprising two carcass plies such that the communication module is positioned in the bead axially on the outside of and against the second carcass ply.
PNEUMATIC TIRE AND METHOD FOR MANUFACTURING THE SAME
Edge separation in a turned-up end portion (5E) of a carcass ply (5) is suppressed. In a pneumatic tire comprising a bead core (4) embedded in a bead portion (3) and a carcass ply (5) turned up and locked around the bead core (4), a rubber sheet (10) is prepared using a wet masterbatch containing natural rubber and/or polyisoprene rubber and carbon black, and the rubber sheet (10) is arranged on at least one of front and back sides of the turned-up end portion (5E) of the carcass ply (5).
PNEUMATIC TIRE
A pneumatic tire that includes a pair of bead cores, a pair of bead fillers connected to the bead cores respectively, a ply which extends between the bead cores; steel chafers disposed outside the ply, and inner nylon chafers disposed outside the steel chafers. The inner nylon chafers extend upward from positions in the vicinity of heels of the bead cores. The pneumatic tire also includes outer nylon chafers are disposed outside the inner nylon chafer.
Method of making a tire with multiple body plies
A method of making a tire includes providing a first body ply having a first width and laying a second body ply above the first body ply. The second body ply has a second width less than the first width. The method also includes laying a third body ply above the second body ply. The third body ply has a third width greater than the first width. The method further includes laying a first bead at a first location above the third body ply, laying a second bead at a second location above the third body ply, laying a first stabilizer ply insert at a third location above the third body ply, and laying a second stabilizer ply insert at a fourth location above the third body ply. The third location is between the first location and the second location, and the fourth location is between the third location and the second location.
PNEUMATIC TIRE
In a tire 2, a contour of an outer surface of the second apex 38 includes: a circular arc C2 that extends inward from an outer end, in the radial direction, of the contour and is convex outward in the axial direction; and a circular arc C3 that is located inward of the circular arc C2 in the radial direction, is in contact with the circular arc C2, and is convex inward in the axial direction. A difference (HtHw/2) between a height Ht from a bead base line to a contact point between the circular arc C2 and the circular arc C3 and a height that is half of a height Hw from the bead base line to a maximum width position is equal to or greater than 10 mm and equal to or less than 10 mm.
Optimized architecture of a civil engineering tire
Radial carcass tire for a civil engineering vehicle, having two bead wires (2) of radial height Ht, and carcass reinforcement made of two layers, the first (1) being radially innermost with a radial height Hdc, is anchored in each bead to form a main part (11) and a turn-up (12). The second layer (3) is radially outside the first layer (1). The free end (A) of the turn-up (12) is at a radial distance from the radially outermost point (21) of the bead wire that is at least equal to 1 and at most equal to 2 times Ht. From the end A of the turn-up (12) to the point B at 85% of the radial height Hdc, the distance between carcass layers is at least equal to 2 and at most equal to 11 times the diameter of metal reinforcers of first carcass layer (1).
HEAVY-DUTY PNEUMATIC TIRE
A heavy-duty pneumatic tire includes a carcass ply including a main portion extending between bead cores and a pair of turn-up portions, a first reinforcing layer of a steel cord disposed in each bead portion in a U-shaped manner, and a second reinforcing layer of an organic fiber cord disposed in each bead portion and at least a part of the second reinforcing layer extending in a radial direction of the tire at an axially outward location of the first reinforcing layer. The second reinforcing layer includes an axially inner second ply and an outer second ply. The outer second ply has an inner end positioned below the bead core. The inner second ply has an inner end located axially inward of the inner end of the outer second ply, and has a substantially same length as the outer second ply in a tire cross-section.
Pneumatic tire for bicycle
The invention relates to a two-wheeled vehicle pneumatic tire (1), preferably bicycle tire, particularly preferably racing bike tire (1), having a tread (2), a tire carcass, tire side walls (3) and two bead regions (4), each with a tire bead with a core (5), wherein the tire carcass comprises two carcass inlays (6,6) wherein the two carcass inlays (6, 6) extend from a zenith region (17) of the two-wheeled vehicle pneumatic tire (1) over the tire side walls (3) as far as the two bead regions (4) and are looped there around the respective core (5) from axially on the inside axially outward and end with carcass inlay ends (7,7) and wherein the two bead regions (4) each have a bead protective strip (8) arranged on the carcass from the outside as protection against chafing. The problem addressed is that of improving the rolling resistance. The problem is solved in that the carcass inlay ends (7) of the inner carcass inlay (6) are covered from the outside by the respective bead protective strip (8), wherein the inner carcass inlay (6) is formed by that carcass inlay of the two carcass inlays (6, 6) which is the radially inner carcass inlay in the zenith region (17). The invention furthermore relates to a two-wheeled vehicle having a tire of said type.
