A pneumatic tire includes: a tire inner surface rubber layer constituting a tire inner surface; and an electrically conductive member, at least a part of the electrically conductive member being disposed on an inner cavity side of the tire inner surface rubber layer. The electrically conductive member includes a knitted fabric including a yarn, at least a part of the yarn having electrical conductivity, the knitted fabric having stretchability. The electrically conductive member is electrically connected to an electrical device provided in the tire. The electrically conductive member is disposed extending along the tire inner surface in a tire radial direction, and a direction in which the electrically conductive member extends aligns with a direction in which the knitted fabric has stretchability. The knitted fabric is configured by mixing a yarn having electrical conductivity and a yarn having non-electrical conductivity.

The present invention discloses a preparation method of polyester cord fabric with low denier and high modulus, including steps of: spinning, reducing melt discharge volume for extruding yarn with denier of 500-1000 D; using high-speed motor and heat roller, spinning speed of 6000-6500 m/min to produce raw yarn; performing initial and repeat twisting of raw yarn by straight twisting machine; performing weaving of twisted yarn using Dornier air-jet loom to produce cord fabric, when weaving and reeding-in, using two into a reed way, adding creel roller bearing and creel single spindle tension control belt to improve uniformity; performing dipping of cord fabric using two-bath dipping, adjusting temperature to 250-260 degrees Celsius, tension to 0.3-2.9 daN/each yarn of key area, running speed of yarn to 55-70 m/min. The polyester cord fabric with low denier and high modulus can reduce rolling resistance and fuel consumption, and improve performance.
