Description

Technical Field

[0001] The utility model relates to the field of spoke wheels, in particular to a tubeless spoke wheel for automobiles. Background Art

[0002] Tubeless wheels are traditional tires without an inner tube. Tubeless tires utilize an airtight layer between the inner wall of the tire and the rim to ensure airtightness, allowing the outer tire to function as a tube. Spoke wheels use spokes to connect the tire's center hub to the rim, providing support. Traditional spokeless tubeless wheels utilize perforations in the rim, with one end of the spoke passing through the perforations and connected to the rim, while the other end connects to the center hub. This solution requires drilling holes in the rim, which affects the tire's seal and reduces the strength of the rim.
