text: Intense investigations repeated by the present inventors in order to solve the conventional problems described above and the like have resulted in finding that a pneumatic tire which meets the object described above is obtained by a pneumatic tire comprising a carcass composed of at least one carcass ply as a skeleton extending in a toroidal form across a pair of beads, at least one belt layer arranged at an outside of a crown part of the carcass in a tire radial direction, a tread part forming a grounding surface part which is provided at an outside of the belt layer described above in a tire radial direction, and an inner liner layer arranged at an inside of the carcass ply in a tire radial direction, wherein a conductive rubber is arranged for a ply coating rubber of one surface, and a non-conductive rubber is arranged for the ply coating rubber of the other surface; assuming that the respective thicknesses thereof are T1 and T2, the carcass ply has a ply having a specific range of T1/T2; and the conductive ply coating rubber is arranged at a tread side, and the non-conductive ply coating rubber is arranged at an inner liner side.
text: Generally, a pneumatic radial tire has a carcass composed of one or more carcass plies that extend in a toroidal shape between a pair of bead portions and reinforce each portion of the tire, and the carcass that constitutes the carcass
text: The carcass is preferable to be comprised of at least one carcass ply containing rubberized polyethylene naphthalate cords therein.
text: Furthermore, in the present embodiment, the carcass 3 is formed with a carcass ply made of organic fibers, and there are not any special restrictions on a material or number of carcass plies.
text: That is, the pneumatic tire of the present invention comprises a carcass composed of at least one carcass ply as a skeleton extending in a toroidal form across a pair of beads, at least one belt layer arranged at an outside of a crown part of the carcass in a tire radial direction, a tread part forming a grounding surface part which is provided at an outside of the belt layer described above in a tire radial direction, and an inner liner layer arranged at an inside of the carcass ply in a tire radial direction, wherein a conductive rubber is arranged for a ply coating rubber of one surface, and a non-conductive rubber is arranged for the ply coating rubber of the other surface; assuming that the respective thicknesses thereof are T1 and T2, the carcass ply has a ply in which T1/T2 is 0.2≤T1/T2≤0.9; and the conductive ply coating rubber is arranged at a tread side, and the non-conductive ply coating rubber is arranged at an inner liner side.

text: The pneumatic tire thus constituted according to the present invention comprises: a carcass composed of at least one carcass ply as a skeleton extending in a toroidal form across a pair of beads; at least one belt layer arranged at an outside of a crown part of the carcass in a tire radial direction; a tread part forming a grounding surface part which is provided at an outside of the belt layer described above in a tire radial direction; and an inner liner layer arranged at an inside of the carcass ply in a tire radial direction, and obtained is the pneumatic tire in which even when different kinds of rubbers are used on the upper and lower surfaces of a ply coating rubber, a stress applied to the tire a direction thereof during travelling of the car are not different on the upper and lower surfaces of the ply to bring about no distortion, so that separation and a distortion of a force applied to the adjacent members can be prevented, which is therefore excellent in durability and prevents accumulation of static electricity during travelling by the ply coating rubber constituted by the conductive rubber having the property described above, which inhibits the tire from rising in an electric resistance with the passage of time, and which is excellent in a reduction in a rolling resistance of the tire.
text: A carcass composed of one or more carcass plies that reinforce each of these parts, The carcass ply is formed by arranging a plurality of carcass cords in parallel at a driving number of 25 to 65 pieces /
text: There is provided a radial carcass 4 composed of one or more carcass plies that reinforce each of these parts 1, 2, 3.
text: In such a pneumatic radial tire, however, when the carcass is comprised of at least one carcass ply containing high-rigidity rubberized polyethylene naphthalate cords therein, the lowering of the breaking tenacity of the belt can be compensated by the increase of the breaking tenacity of the carcass to mitigate the tension bearing ratio of the belt.
text: Moreover, the carcass 4 is comprised of at least one carcass ply containing rubberized polyethylene naphthalate cords therein.
text: Furthermore, in the present embodiment, the carcass 3 is formed with a carcass ply made of organic fibers, and there are not any special restrictions on a material or number of carcass plies.
