Patent number: 7281553Abstract: A pneumatic radial ply tire incorporating a crown reinforcing structure comprises at least one reinforcing hoop located approximately on the equatorial plane and disposed radially inward of the tread and radially outward of the carcass structure. The hoop is surrounded or encased by a layer of elastomeric transition material providing a flexible structural connection between the hoop and the adjacent carcass structure and belt structure. The hoop may have a substantially lenticular shape, or a complex shape with two thickened sections or lobes connected by a thin waist-like section, or a shape and a location that is asymmetric with respect to the equatorial plane of the tire, and may be made by winding a thin strip of material such as UHMWPE in an elastomeric matrix. The hoop may replace the belt structure of the tire.Type: GrantFiled: December 14, 1999Date of Patent: October 16, 2007Assignee: The Goodyear Tire & Rubber CompanyInventors: Alain Emile Francois Roesgen, Laurent Colantonio, Filomeno Gennaro Corvasce

Publication number: 20060130951Abstract: A pneumatic tire is capable of operation during underinflated condition and the construction of sidewalls are configured to compensate for negative cambers acting upon the tire. The inboard side of the tire is softened in comparison to the outboard side of the tire. This is achieved by either forming an asymmetrical tire in either the tire profile or the internal construction.Type: ApplicationFiled: December 20, 2004Publication date: June 22, 2006Inventors: Marc Hedo, Johan Dahlberg, Walter Allen, Laurent Colantonio, Filomeno Corvasce

Publication number: 20060016539Abstract: A self-supporting pneumatic tire, capable of continued operation during under-inflation conditions, has at least one insert located in each tire sidewall. Forming the interior surface of the self-supporting tire is a stiffening layer of material having characteristics similar to that of the insert. In the tread region of the tire, and radially inward of the innermost carcass layer, and possibly in the interior bead region of the tire, is a partial inner liner layer of the bromobutyl rubber.Type: ApplicationFiled: August 30, 2005Publication date: January 26, 2006Inventors: Laurent Colantonio, Anne Peronnet-Paquin, Filomeno Corvasce, Alain Roesgen, Frank Philpott

Patent number: 6843293Abstract: A pneumatic radial ply tire (86, 104) having a tread (106), a carcass (96, 108) with two sidewalls (88a, 88b, 116a, 116b), a radial ply structure (98, 110), and a belt structure (103, 117) located radially between the tread and the radial ply structure. Each sidewall is reinforced with at least one wedge insert (89a, 89b, 118a, 118b, 120a, 120b) which comprises alternating regions (90a, 90b, 122a, 122b) of flexible material and layers (91a, 91b, 124a, 124b) of stiffer material. The layer (91a, 91b, 124a, 124b) of stiffer material constrain the lateral expansion of the wedge insert (89a, 89b, 118a, 118b, 120a, 120b) during runflat operation to provide good riding comfort during normal inflation operation and good sidewall reinforcement during runflat operation.Type: GrantFiled: December 16, 1999Date of Patent: January 18, 2005Assignee: The Goodyear Tire & Rubber CompanyInventors: Filomeno Gennaro Corvasce, Anne Therese Peronnet-Paquin, Laurent Colantonio, Alain Emile François Roesgen

Patent number: 6814120Abstract: Fabric treatment layers (130a, 130b, 132a, 132b) are deployed in the sidewall regions of a runflat tire (100) having a metal-reinforced first ply (120). In one embodiment, parallel cord, reinforced fabric treatment layers (130a, 130b, 132a 132b) sandwich the metal forced first ply (120) and inhibit buckling of the reinforcing cords (70) of the first ply during runflat operation when the ply cords or wires are bearing compression loads. In another embodiment, a single woven fabric treatment layer (170a, 170b) is disposed in each sidewall region (152,154) at a location immediately axially inward of the metal-reinforced first ply (160).Type: GrantFiled: December 12, 2001Date of Patent: November 9, 2004Assignee: The Goodyear Tire & Rubber CompanyInventors: Gia Van Nguyen, Laurent Colantonio

The cord-reinforced flat strip is wrapped helically around the green tire carcass prior to blowup into the characteristic toroidal shape of a tire carcass. In one embodiment, the underlay structure is disposed between breakers and the radial ply structure. In another embodiment, the underlay is disposed between the radial ply structure and the innerliner. In another embodiment, the afore described underlay structure has an additional and structurally contiguous beam made of elastomeric material.Type: GrantFiled: July 15, 2003Date of Patent: September 21, 2004Assignee: The Goodyear Tire & Rubber CompanyInventors: Walter Dale Allen, Laurent Colantonio, Frank Philpott

Patent number: 6763866Abstract: A pneumatic radial ply tire (50) has a tread (52), a carcass (61) with two sidewalls (77, 78), a single radial ply (70) reinforced with inextensible metal cords, two annular beads (36a′, 36b′), and a belt structure (58) located radially between the tread and the radial ply structure (56). Each sidewall (77, 78) is reinforced with wedge inserts (59a, 59b) containing stiffener layers (72a, 72b, 73a, 73b) that carry the compressive loading to which the tire is subjected during runflat operation. The incorporation of wedge-insert stiffeners (72a, 72b, 73a, 73b) provides a light-weight runflat tire having a simplified construction.Type: GrantFiled: July 5, 2001Date of Patent: July 20, 2004Assignee: The Goodyear Tire & Rubber CompanyInventors: Gia Van Nguyen, Laurent Colantonio

Patent number: 6695025Abstract: The tire (70) of the invention incorporates a carcass ply cord material (93) with variable modulus of elasticity to provide an active sidewall structure (82a, 82b). The variable modulus cord material is incorporated in the axially outwardmost ply (90) of a carcass (80) having two plies (88, 90) separated by elastomeric inserts (89a, 89b) in the sidewalls (82a, 82b). The outer ply cord material (93) provides an increased modulus of elasticity with an increase in elongation. The inner ply cords (91) have a modulus that substantially exceeds that of the outer ply cords (93) under normal loads in the inflated mode. Thus, the inner ply (88) dominates the structural response of the sidewalls (82a, 82b) at normal loads in the inflated mode. Under severe sidewall deflection, such as when the tire is uninflated, the outer ply cord (93) is elongated, increasing its modulus of elasticity and thus, shifting the load from the axially inwardmost ply (88) to the axially outwardmost ply (90).Type: GrantFiled: October 17, 2001Date of Patent: February 24, 2004Assignee: The Goodyear Tire & Rubber CompanyInventors: Alain Emile Francois Roesgen, Laurent Colantonio, Marie-Rita Catherine Amelie Thise-Fourgon

Publication number: 20030111152Abstract: A pneumatic tire bead area construction for improved chafer cracking resistance during run-flat (uninflated) tire operation comprises a chafer reinforcement fabric component that is positioned at the surface of the chafer wherever it may contact the wheel rim flange during normal tire operation, and especially during uninflated tire operation. The fabric component may be anchored by extending it around the bead. The fabric component may replace the toeguard, thereby further reinforcing and protecting the bead area by extending the chafer reinforcement fabric component along the surfaces of the bead area wherever surfaces of the tire can contact the wheel rim and rim flange during mounting of the tire and during operation of the tire.Type: ApplicationFiled: December 6, 2001Publication date: June 19, 2003Inventors: Laurent Colantonio, Fernand Antoine Joseph Fourgon, Frank Philpott, Frank Schmitz, Alain Emile Francois Roesgen

Patent number: 6453961Abstract: A pneumatic radial ply runflat tire 1000 for a vehicle has a tread 1012, a carcass 1022 comprising at least one radial ply 1030 and two sidewalls 1016 each reinforced by a circumferentially disposed crescent-shaped wedge insert. Each insert has an elastomeric porous section 1042 embedded in an elastomeric stiffer layer 1044 of the insert 1040. When the tire is normally inflated, the porous section 1042, and hence the insert as a whole, is flexible, thereby providing comfortable driving characteristics. Under runflat (deflated tire) conditions, the pores in the porous section 1042 collapse, and the porous section 1042 stiffens, and hence the insert as a whole becomes stiff enough to support the load of the vehicle.Type: GrantFiled: June 1, 2000Date of Patent: September 24, 2002Assignee: The Goodyear Tire & Rubber CompanyInventors: Laurent Colantonio, Alain Emile Francois Roesgen, Filomeno Gennaro Corvasce
