Abstract

A tubeless tire includes a tread portion, two sidewalls, an interfacing material integrally formed between the two sidewalls of a pliable, flexible yet reliable material, two beads extending outwardly from the tire, delimiting a section formed by the interfacing material, and an air valve stem provided on the interfacing material. The thickness of the interfacing material is substantially the same as the thickness of the two sidewalls, and the beads project outwardly of an outer surface of the interfacing material. The beads are disposed in a position such that when the tire is mounted on a rim, the beads will fit within the rim, when the tire is inflated on the rim using the air valve stem, the interfacing material will expand, causing the beads to fit tightly within the rim, thus fixing the tire on the rim, and there is no sealing layer within the tire.

Dependent claims

A tubeless bicycle tire comprising:

a tread portion;
two sidewalls, each adjacent one end of the tread portion and being thinner than the tread portion;
an interfacing material integrally formed between the two sidewalls of a pliable, flexible yet reliable material;
two beads extending outwardly from the tire, delimiting a section formed by the interfacing material;
an air valve stem provided on the interfacing material, and
wherein a thickness of the section formed by the interfacing material is substantially the same as a thickness of the two sidewalls, and the beads project axially outwardly and radially inwardly of an outer surface of the interfacing material,
wherein the beads are disposed in a position such that when the tire is mounted on a rim, the beads will fit within the rim,
wherein when the tire is inflated on the rim using the air valve stem, the interfacing material will expand, causing the beads to fit tightly within the rim, thus fixing the tire on the rim, and
