Patent number: 11186054Abstract: The present invention includes tire treads having a sipe (18) and a void feature (22) in fluid communication with the sipe. Particular embodiments of the present invention also include methods for forming the same. In various embodiments, the sipe has a length, a height, and a thickness that is variable across the length and height of the sipe. The thickness of the sipe includes a thick portion (24) and a thin portion (26), the thick portion at least partially extending around a perimeter of the thin portion. In particular embodiments, the void feature (22) which is in fluid communication with the sipe extends primarily in a direction of the sipe length and has a width extending in the direction of the sipe thickness equal to or greater than substantially 1 millimeter.Type: GrantFiled: September 30, 2016Date of Patent: November 30, 2021Assignee: Compagnie Generale des Etablissements MichelinInventors: Mark Collett, Francois Hottebart, Constantin Lazar, Martin Lipham

Patent number: 10766313Abstract: Tire tread including one or more tread elements arranged between a pair of discontinuities extending in a direction of the tread width. The first and second longitudinally-spaced sides of the tread element are spaced-apart in a direction of the tread length. The first longitudinally-spaced side is oriented at an average first-side angle relative to the depthwise direction of the tread and the second longitudinally-spaced side is oriented at an average second-side angle relative to the depthwise direction of the tread. An average inclination angle comprising a combined average of the average first side-angle and the second side-angle for all of the one or more tread elements along the first and second longitudinally-spaced sides is substantially greater than zero.Type: GrantFiled: June 30, 2014Date of Patent: September 8, 2020Assignee: Compagnie Generale des Etablissments MichelinInventors: Mark Collett, Francois Hottebart

Publication number: 20180326794Abstract: The invention includes tire treads, tires including the tire treads, and methods of forming a tire tread. The tire tread includes a length extending in a lengthwise direction, a width extending in a lateral direction, and a thickness extending in a depth-wise direction from an outer, ground-engaging side of the tread. The tire treads further include a sipe having a length, a height, a width, a thickness extending in a direction of the sipe width, and a cross-section taken along a plane extending in a direction of the sipe width and height, where the cross-section twists as the sipe thickness extends along the length of the sipe. Method of forming the tire tread includes molding into the tread a sipe and a void feature as recited herein.Type: ApplicationFiled: October 28, 2016Publication date: November 15, 2018Applicant: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: Mark COLLETT, Francois HOTTEBART, Xavier NEAU, Timothy WHITE
