  • Pneumatic tire having multiple modulus body cord to reduce rolling resistance
    Patent number: 6971427
    Abstract: A pneumatic tire includes a body having a plurality of main body cords. The tire includes an upper section above the maximum section width and a lower section below the maximum section width. The modulus of the body cords is configured to be larger in the lower section than in the upper section. This modulus ratio decreases the rolling resistance of the tire. The increased modulus in the lower section is achieved by providing intermediate body cords disposed between the main body cords. In another embodiment, the increased modulus is achieved by changing the material and/or size of the cords in the lower section.

  • Pneumatic tire having a body cord insert that reduces the rolling resistance of the tire
    Patent number: 6595256
    Abstract: A pneumatic tire includes a body having a plurality of main body cords. The tire includes an upper section above the maximum section width and a lower section below the maximum section width. The modulus of the body cords is configured to be larger in the lower section than in the upper section. This modulus ratio decreases the rolling resistance of the tire. The increased modulus in the lower section is achieved by providing a body cord insert wrapped around the bead core and bead filler. The ends of the body cord insert are disposed against each other so that the entire bead filler is surrounded. The body cord insert extends substantially over the entire lower section of the tire.
