Latest Patents

One of his latest patents is titled "Tire tread to compensate residual aligning torque." This invention modifies the tread of a rib type tire by providing draft angles in lateral grooves of selected ribs. This modification compensates for the tire's residual aligning torque (RAT), allowing the vehicle to maintain straight ahead motion without steering pull. The draft angles are achieved by inclining the radial centerline of the lateral grooves, resulting in tread blocks that are sloped forward and backward during the vehicle's forward motion. This innovative design introduces changes in the contact patch of the tire with the ground surface, effectively altering longitudinal tangential stress and inducing a torque to counteract the inherent residual aligning torque.

Another significant patent by De Reynal is the "Radial tire tread and method of mounting a tire with said tread." This design features lateral or transverse grooves on the shoulder ribs that incline from the normal to the contact surface in one direction, while the grooves in the center of the tread width are inclined in the reverse direction. This unique tread design improves wear rates and promotes uniform wear on a drive axle with proper tire rotation. Additionally, reversing the direction of rotation on the non-drive axle leads to more even wear, potentially reducing vibration and noise.
