  • Patent number: 8925606
    Abstract: A tire comprising a reinforcing structure of the carcass type and comprising under the tread strip a crown reinforcing structure comprised of at least one layer of reinforcing elements. At least the surface of the tread strip comprises a first polymer compound extending at least into the region of the equatorial plane and at least one second polymer compound having physicochemical properties that differ from those of the first polymer compound, the crown reinforcing structure comprising at least one layer of circumferential reinforcing elements which are distributed in the transverse direction with a variable pitch and the pitch between the circumferential reinforcing elements being at a minimum in the region of the layer of circumferential reinforcing elements that radially face the ends of the first compound.

  • Patent number: 6842720
    Abstract: A method of controlling uniformity during tire manufacture includes the steps of selecting a target attribute and assigning a target value thereto, measuring the target attribute in a subject tire at a first rotational speed approximating highway speed and measuring in the subject tire indicator attributes a second rotational speed lower than the first rotational speed. The indicator attributes are condensed via a multivariate process to determine which attributes are the most strongly related to the target attribute. Next, a plurality of predictors for the target attribute is determined, each predictor having components including at least one indicator attribute. From the plurality of predictors, at least one best predictor is selected.

  • Patent number: 6729006
    Abstract: A process for demounting a tire P, and a tread-bearing support S internal thereto, from an integral mounting rim J, which comprises first and second rim seats, the two rim seats being inclined towards the outside and extended axially to the outside by projections of low height. The process includes the steps of inserting, into a lubricated gap between the toe of the first bead Bo and the corresponding rim seat, a demounting insert I in the form of a portion of a circular ring of triangular meridian section of small dimensions, and then ejecting the first bead Bo from the rim J before or simultaneously with the ejection of the tire/support assembly.

  • Patent number: 5944082
    Abstract: The tread of a rib type tire is modified to provide draft angles in lateral grooves of selected ribs to compensate the tire's residual aligning torque (RAT). This allows the vehicle to have straight ahead motion with no steering pull. The draft angles are achieved by inclining the radial centerline of the lateral grooves to be sloped forward on one side of the midcircumferential plane and sloped backward on the other side of the midcircumferential plane. The centerline draft angle results in tread blocks sloped forward and backward during forward motion of the vehicle. The sloping tread blocks produces an effective rolling radius change on selected ribs of the tread pattern. Effective rolling radius of selected ribs is a concept introduced to explain the physical relationships that exist in the contact patch of the tire with the ground surface.
