Abstract: A tire is disclosed, including a plurality of blocks, each has an outer surface bulging outward and two lateral walls. An extension line is defined on the surface of each flat segment of each block. Each extension line has a first point on the flat segment. A first horizontal reference line is defined by connecting two first points. A second horizontal reference line is defined on the outer surface with two ends thereof contacting the outer surface. The second horizontal reference line is 0.85 times as long as the first horizontal reference line. A vertical distance between the outer surface and the second horizontal reference line is 0.2-0.8 mm. Whereby, the tire could provide good drainage performance and adequate grip.

Abstract: A tire includes a carcass and a tread member. The carcass has a tread portion, two sidewalls on opposite sides of the tread portion, and two beads on distal ends of the sidewalls. The tread member has a tread protective layer provided on an outer side of the tread portion of the carcass and a skin layer provided on the tread protective layer. In an embodiment the tire further includes a sidewall protective layer and a bead protective layer to protect the sidewalls and the beads of the carcass. The tire may have a good airtight condition and a light weight.

Abstract: A tubeless tire includes a carcass covered with a first impermeable layer and a second impermeable layer. The first and second impermeable layers have portions overlapped to obtain a good airtight property. The first impermeable layer includes a composite compound with strength reinforced powder, an intersection carrier and rubber that the tire is strengthened and light in weight. The tubeless tire of the present invention further has a thread on the first impermeable layer to contact ground.

Abstract: A tire includes a tread portion with two sidewalls integrally connected thereto and each of the sidewalls includes a lip so as to be engaged with a wheel rim. Two reinforcement layers are respectively secured on two respective outsides of the two sidewalls and each reinforcement layer is composed of adhesive, mineral particles and/or metal particles. The reinforcement layer has a smooth outer surface and efficiently prevents being penetrated by foreign objects.

Abstract: A reinforcement structure for a valve of tires includes a tube having a hole defined through a wall thereof and an enlarged base of a valve is connected to the hole. A rubber made reinforcement pad is mounted on the base and connected to the tube wherein a length of the reinforcement pad is equal to or larger than twice of a width of the reinforcement pad.

Abstract: A tire frame structure used in electromotive scooters and small size motor vehicles comprises a tire frame being an integrally molding structure; a periphery round portion being formed around the periphery of the tire frame; an annular trench being formed in the periphery round portion; the annular trench having two opposite inner walls; an inner side of each inner wall having an annular protrusion for receiving the lips of a tire; a receiving space being formed between the annular protrusion and the annular trench; and an air valve hole formed in the annular trench. The air valve hole obliquely penetrating through a bottom of the annular trench toward an outer side of the tire frame.

Abstract: A small tire used in electromotive scooters and small size motor vehicles comprises a tire having an annular groove; an annular bottom of the annular groove being installed with a protecting layer with a predetermined thickness for protection the tire from being pierced; the tire being formed with a pair of tire lips at two sides of an opening of the tire; a tire frame being combined with the pair of tire lips; the ring having two round walls at two outer opposite sides of the tire ring; an annular trench being formed between the two round walls; an inner side of each round wall protruded with an annular protruded wall; a receiving space being formed between the protruded wall and the round wall for receiving a respective tire lip; and the tire lips being tightly adhered to the annular protruded walls and the round walls.

Abstract: A tire with a lip edge structure comprises a tire body having an opening; two lip edges formed on two sides of the opening; two adhering portions; each lip edge having an adhering portion; a steel beam being embedded in the adhering portion for retaining the tire body; the adhering portion being an enlarged cambered portion, which protrudes at an outer portion of the tire body; two slide-proof cloths; an outer side of each adhering portion being enclosed by one of the mono-nylon slide-proof cloth. The slide-proof cloths are made of mono nylon with a rubber layer; the rubber layer has a thickness between 0.3 mm to 2.0 mm. The slide-proof cloth is interleaved by mono-nylon of 10˜50*10˜50 EPI and is interleaved by mono-nylon with each yarn being ranged from 210 Diner to 840 Diner. The lip edges are made of Kevlar Bead.

Abstract: A tire structure includes a breaker composed of nylon and kevlar, and a tread is attached on an outside of the breaker. The breaker includes two sidewalls which are formed by the nylon and kevlar woven alternatively with each other at an angle.
