Patent number: 10953700Abstract: The tread has a total axial width W and a wearable thickness PMU of material and has at least four grooves on each side of a midplane that divides the tread axially into two parts. The grooves divide the tread into a middle, intermediate and edge regions 6. The middle region has an axial width Lm of at least 30% and at most 60% of the total width W. The total volume void ratio when new is less than 17%, and the middle region has a volume void ratio that is less than half the total volume void ratio. The middle region comprises a plurality of transverse sipes opening into the grooves, and the sipes have depths at least equal to 75% of the depth of the grooves. The number of transverse sipes in the middle region is greater than the number of transverse sipes on each intermediate or edge region.Type: GrantFiled: February 2, 2015Date of Patent: March 23, 2021Assignees: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELIN, MICHELIN RECHERCHE ET TECHNIQUE, S.A.Inventors: Maxime Rolland, Fabien Marlier, Ronald Cress, Ralston Moore

Patent number: 10369846Abstract: The tread has a total width W and two main grooves. The main grooves divide the tread into a middle region and edge regions. The middle region has an axial width Lm that is 45% to 70% of the total width W. The volume void ratio of the tread when new is less than 17%. An internal surface extends parallel to the tread surface when new and is in contact radially with the innermost points of the deepest main grooves. The middle part has a plurality of transverse sipes, each of which has a depth at least equal to the depth of the main grooves. The transverse sipes open into the main grooves. The middle region has a volume void ratio when new that is less than half the total volume void ratio of the tread, and at least one circumferential channel appears when the tread becomes part worn.Type: GrantFiled: February 2, 2015Date of Patent: August 6, 2019Assignees: Compagnie Generale Des Etablissments Michelin, Michelin Recherche Et Tehcnique, S.A.Inventors: Fabien Marlier, Maxime Rolland, Damien Bardin, Christophe Gayton, Tony Zivkovic

Patent number: 9783004Abstract: A tire tread is provided having a layered design that includes bridged and unbridged circumferential grooves during earlier stages of tread life while transverse and unbridged circumferential grooves are provided at later stages of tread life. Together, the combination of grooves can provide desired wet adherence performance without unacceptable compromises of tread wear and/or rolling resistance. Pockets can also be provided at the end of the transverse grooves to increase the volume available for receipt of water during wet traction.Type: GrantFiled: April 30, 2013Date of Patent: October 10, 2017Assignee: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventor: Maxime Rolland

Publication number: 20160368322Abstract: A tire is provided having a body ply that is displaced from the conventional equilibrium curve along the shoulder and upper side wall region of the tire in a manner that provides more uniform inflation growth along the crown region so as to reduce differences in rigidity between the center and shoulders of the tire, reduce load sensitivity, and/or decrease the propensity for cracking. A method for designing or constructing such a tire is also provided.Type: ApplicationFiled: February 27, 2014Publication date: December 22, 2016Inventors: Brian GANNON, William B. CLAYTON, Michael C. ANDREWS, Maxime ROLLAND, Daniel McEachern HICKS

Patent number: 9434211Abstract: A tire tread having a layered design is provided. In a first layer of the tread, sipes extend transversely to provide traction in the first stage of the wear life of the tread. In a second layer of the tread, the width of the sipes along the circumferential direction is increased to provide for improved traction in a second stage of the wear life. The increased width is provided by a void that opens to a circumferential groove only along one end. Because the void opens only along one end, a decrease in acoustical effects such as drive by noise can be provided.Type: GrantFiled: April 30, 2013Date of Patent: September 6, 2016Assignees: MICHELIN RECHERCHE et TECHNIQUE S.A., COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: Maxime Rolland, Dmitri Tsihlas
