Abstract: A tire pattern structure including a tread pattern and a sidewall pattern is formed by uniformly distributed patterns in the circumferential direction of a tire. The tread pattern is formed by two long spoon-shaped pattern blocks symmetrical with respect to the center of the tire tread and the axial direction of the tire. A spoon-shaped pattern block group is across the center of the tire tread and each interlaced and mapped sideway along the center of the tire tread formed by upper and lower long spoon-shaped pattern block groups. The two spoon-shaped patterns are coupled from a head block to a handle block and bent at the tire shoulder to couple the sidewall pattern formed by the upper and lower sidewall pattern blocks which are formed by a quadrilateral block of two protrusions and three recessed blocks to overcome rough terrains and provide excellent mud and water removing performance.

Abstract: An inflatable tubeless tire includes a carcass, a bead at the lower edge of both sides of the carcass; a cladding layer, continuously covering the bead from the exterior to the interior of the carcass, and both ends of the cladding layer having an overlapped portion between each carcass and a tread and continuously extending to form an external covered portion for covering an area from the outer surface to the bead, and the portion of both sides of the cladding layer covering the interior of the carcass being an internal covered portion, and the uncovered position in the carcass being an elastic portion, and each inner surface in the carcass and the cladding layer jointly forming a gas chamber; at least a separator, partially disposed on a wall surface of the gas chamber for isolating each elastic portion and the inner surface without sticking to one another of the carcass; an air valve module, passing between each opening and the through hole, and having a film fixed to the elastic portion; and an extending

Abstract: A bicycle tubeless tire includes a tread and two sidewalls are formed on two sides of the tread. Each sidewall has a lip formed on the distal edge thereof. An installation unit is integrally formed with each lip. Each lip includes an inside, an underside and an outside. The underside and the outside of each lip are engaged with an engaging portion at the inner bottom of the rim when the tire is installed to the rim. The lips do not shift by the engaging portions of the rim. Each of the underside and the outside is a flat side such that the contact area between the lips and the rim is increased to have better air-tight features. The outer face of each lip is a flat face to be installed to the rim without flanges. The deformation of the sidewalls of the tire, and the wind resistance are reduced.

Abstract: A bicycle wheel rim includes a rim having a hollow inner part and an outer part which is integrally formed with the inner part. An opening is defined in radial direction of the outer part. A connection unit is formed in the outer part and includes two seats located at an inner bottom of the opening, and two sidewalls extending from the two seats. Two engaging portions are respectively formed on the two seats and located apart from each other. Each sidewall has an outside, an inside and a top face which is connected between the outside and the inside. The inside is a flat inside without any lip or flange. The sidewalls have better strength and protect the sidewalls of the tire from being deformed.
