Abstract: A pneumatic tire 1 including a cylindrical annular structure 10; a rubber layer 11 that will become a tread portion, provided along a circumferential direction of the annular structure 10, on an outer side 10so of the annular structure 10; and a carcass portion 12 including fibers covered with rubber, provided on both sides 2S in a direction parallel to a center axis (Y-axis) of a cylindrical structure 2 including the annular structure 10 and the rubber layer 11. In a meridian cross-sectional view of the structure 2, an outer side 11so of the rubber layer 11 and the outer side 10so of the annular structure 10 have the same form.

Abstract: A tire for a vehicle comprises, an inner wheel (12) adapted to mount to a vehicle having a radially outer surface (34). A first ring (16) is annular and concentric with the inner wheel (12) and has a radially outer (40) and a radially inner (38) surface. An annular inner-tube (14) is securedly positioned between the inner wheel (12) and the first ring (16). A second ring (18) has a radially outer surface (46) and a radially inner surface (44) adapted to mate with first ring (16). A tread (20) is secured to radially outer surface (46) of said second ring (18).

Abstract: A wheel comprising means for providing one or more protrusions in a ground-engaging surface of the wheel. In some embodiments, the wheel comprises a first hub, a tire mounted on the first hub, a second hub rotatable with respect to the first hub, and means for deforming the tire in a generally radial direction in response to relative rotation between the first and second hubs. The invention also provides a wheel cover comprising an outer surface having one or more protrusions and, when the cover is fitted to a wheel, the outer surface of the cover provides the ground-engaging surface of the wheel. The wheel and wheel cover of the invention are particularly suited for use with prams and similar vehicles in order to impart a rocking motion to the pram during use.

Abstract: An inner tube for a vehicle tire, which includes a base having air chambers in two opposite side walls thereof and zigzag insertion slots around the periphery of each of the side walls, a multi-cell rubber tube mounted on the base between its side walls and defining a plurality of zigzag insertion slots arranged one over another around a center opening thereof and an annular insertion slot surrounding the zigzag insertion slots for mounting patching glue, and a plurality of breaker assembles respectively mounted in the zigzag insertion slots in the base and the multi-cell rubber tube.

Abstract: An inner tube for a vehicle tire, including a base, the base having two outer walls, two inner walls, an annular air chamber connected between the inner walls, and a plurality of rubber coated breakers retained between the inner walls and the outer walls and arranged in a zigzag manner around the axial central axis of the base, and a multi-cell tube mounted around the annular master air chamber between the inner walls of the base, the multi-cell tube having arched cells of different sizes arranged around its center, a plurality of foamed rubber blocks and a plurality of glued breakers alternatively plugged into the arched cells, and a layer of patching agent covered over the arched cells to seal the foamed rubber blocks and the glued breakers in the arched cells.

Abstract: A vehicle inner tube includes an inflatable tube, a protective tube mounted around the inflatable tube for protection, the protective tube formed of a plurality of air balls and having recessed breaker seats equiangularly spaced around its inner diameter, a plurality of breaker units respectively mounted on the inner diameter of the protective tube and partially overlapped on one another and adhered to recessed breaker seats in the protective tube, the breaker units each including a flexible breaker holder having two reversely horizontally extended side insertion slots and a downwardly obliquely extended bottom insertion slot, two side breakers respectively directly inserted into the horizontal insertion slots and partially projecting out of the breaker holder at two opposite sides, and a bottom breaker inserted into the bottom insertion slot and secured thereto by glue means, an endless cover layer covered on the protective tube and adhered thereto by glue means, the endless cover layer comprising a pluralit

Abstract: A lightweight, filler core tire construction for automotive and other vehicles, having a flexible composite outer layer structure and an inner flexible honeycomb core with a radial relief and said honeycomb is bonded to said outer layer, eliminating thus fully or partially pressurized air from the tire and increasing the safety of driving, damage resistance, and minimizing servicing of the tire. The structures are preferably made of a polyurethane polymer and various fibers and do not require a split rim for mounting and dismounting said tire.

Abstract: The deformable driving band (3) or similar comprises passage means (2) passing through the band and opening out, towards the inside, at right angles to pockets (5) or similar provided in a compressible strip (6) extending over the whole driving band, the assembly being such that a suction phenomenon increasing grip is created by the compressible strip (6) and the packets (5) in deformation zone of the driving band (3) corresponding to an expansion phase of said pockets (5).

Abstract: The tire for heavy load consists of a multi-layered flat ring held in the axial and radial direction by a two-part metal felloe and supported between the felloe by air.

Abstract: The present invention relates to a vehicle tire having a continuous solid elastic annularly shaped cushion for encircling a vehicle wheel and an inflatable tubeless tire mounted around the outside periphery of the cushion.
