Latest Patents
One of Harle's latest patents involves a tire comprising a tread formed by multiple elastomer blends. This tire features a radial carcass reinforcement and a crown reinforcement, capped radially by a tread connected to two beads by two sidewalls. The tread consists of at least two layers of blended elastomeric compounds that are radially superposed, with a voids ratio that is lower in the central part than at the axially outer parts. The first layer of blended elastomeric compounds includes a first blended elastomeric compound that extends into the region of the equatorial plane, along with at least two axially outer parts formed of a second blended elastomeric compound. The first blended elastomeric compound has a macro dispersion Z-value higher than 65 and a maximum tan(δ) value lower than 0.120. Additionally, the complex dynamic shear modulus G* 1% at 100°C of the second blended elastomeric compound is at least 10% higher than that of the first blended elastomeric compound.
