Latest Patents

One of his latest patents is for a pneumatic tire with an improved tread. This tire design features a tread where the central part comprises at least two rubber compounds, making up at least 90% of its volume. The first compound is positioned radially on the outside of the second compound and constitutes between 40% and 60% of the volume of the central part. The second rubber compound has a Shore hardness that is at least equal to the first compound plus an additional 5. The dynamic losses at temperatures of 0° C and 23° C are at least equal to those of the first rubber compound. Additionally, the axially outer parts of the tread are made up of a third compound that has lower stiffness and hysteresis than the first compound.

Another patent involves a tire tread comprising a block with a plurality of cutouts. This design features an elongate block of rubbery material that extends in a circumferential direction of the tire. The block includes a ground contact surface defined by first and second lateral walls. It also comprises a series of oblique cutouts that open onto either lateral wall and extend to cutout ends that do not open onto the walls. The distribution of these cutouts is such that when one cutout reaches its end, another cutout begins at the same circumferential level on the elongate block.
