Abstract:
A tire for vehicles which does not require pressurization by means of a pressurized fluid has a tread, two sidewalls, and two beads which are attached to a wheel rim made of elastomer material, and is provided with at least one tubular reinforcement body which is associated with the tread; each of the sidewalls having a respective homogeneous resilient annular membrane, a straight generatrix of which forms an angle (A) other than 90° with the axis of the tire; the membranes being stretched radially between the tread and the beads such as to be pre-tensioned in the absence of external loads acting on the tire.
Abstract:
A pneumatic tire including a tread portion, a pair of sidewall portions, a pair of bead portions, and a carcass extending between the bead portions through the tread portion and sidewall portions, wherein the tread portion is provided radially inside the carcass with a tread tape having a thickness of not more than 2.0 mm and having a tensile elastic modulus larger than any rubber existing between the tread tape and the adjacent carcass cords. A method of manufacturing the pneumatic tire includes vulcanizing a main body of the tire, excepting the tread tape, and attaching the tread tape onto the inside of the vulcanized tire main body.
Abstract:
A first tire having a cavity filled with cured and foamed elastomeric material and a recycled foamed elastomeric material. The recycled foamed elastomeric material was removed from a second tire for recycling in the first tire.
Abstract:
A device for serving as a wheel for motor vehicles, where the wheel has its tire tread replaceable when it is worn out via unique rims and molded tire features. An alternate internal structure prevents the tire from “going flat” or “blowing out” when it is punctured or cut. In one variation the tire can be used with existing rims and can be retro-fitted into existing tire by mating the tires with this invention's “Non-Flat Tire” internal element and special rim. A variation of the “Non-Flat Tire” system uses spring-like materials for its tire core that is shaped similar to a tire's inner tube, and functions like an “air-filled” tire, but the absence of the use of air in this unique configuration gives it the “Flat Tire Prevention” effect.
Abstract:
Bicycle wheels have integral reflective areas to increase visibility of the bicycle. These areas show through portions of the wheel tread, so that the tread protects the reflector material from wear. The reflecting areas are scattered over the wheel and situated at a variety of angles with respect to the plane of the wheel so that reflectors are always situated to reflect light from the sun, a street lamp, or car headlights. A bicycle tire of the conventional sort having a tube and removable outer tire having tread is used. The outer tire has holes formed in it interspersed among the raised areas of tread. Reflecting material in sheets is placed between the outer wheel and the tube. Preferably, the reflecting material is affixed to the outer tire, and is coated with a protective coating.

Abstract:
A runflat radial ply tire (70) having a thread (72), a carcass (86) and a belt structure (74) radially located between the thread and the carcass has two sidewalls (80, 82) each reinforced with a circumferentially disposed wedge insert (50a′, 50b′) having a saw-tooth cross-sectional shape. The saw-tooth cross-sectional shape of each wedge insert (50a′, 50b′) is defined by a plurality of circumferentially disposed segments (52a–52e), each of which is separated from adjacent segments by circumferentially disposed grooves (54a–54d). During heavy loading of the tire, or during runflat operation, the radially loaded sidewall portions deform until the grooves (54a′–54d′) undergo closure.

Abstract:
A tire is manufactured on standard tire building equipment and cured in standard curing presses. The tire tread has at least one deep circumferentially extending groove. Within the groove is a separately assembled ring. The ring may be fitted into the deep groove after vulcanization of the tire. For very wide tires, two grooves with two external rings may be used or more than two grooves and beads, depending upon the tire width.
