Abstract: A non-pneumatic tire includes a tread layer and a spoke layer including an inner cylinder and several spoke assemblies. The tread layer is annular and has a maximum outer diameter of the non-pneumatic tire and is adapted to be in contact with a ground. The spoke assemblies extend in a radial direction of the non-pneumatic tire and are arranged around an axial core of the non-pneumatic tire. An end of each spoke assembly is connected to the inner cylinder, and another end thereof is connected to the tread layer. Each spoke assembly includes a straight spoke, a bending spoke, and a connecting rib. Each bending spoke includes a first segment and a second segment, which are not connected in a straight line. Each connecting rib has a first end connected to the straight spoke and a second end opposite to the first end and connected to the bending spoke. When the non-pneumatic tire bears a weight and is squeezed, the spoke assemblies do not get in contact with one another.

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.
