Abstract: Embodiments of the present invention provide a novel solution for preventing pinch flats and installation flats incurred by an inner tube as a result of the wheel striking an object. Embodiments are directed to an inner tube protector that fits within a tire and provides mechanical protection to the inner tube against tire strikes. Embodiments may include an inner region adapted to support an inner tube installed around a rim of a wheel. Additionally, embodiments may include an outer region adapted for insertion within and against the rim lip of the rim which provide protection to the inner tube responsive to the wheel striking an object. As such, embodiments may be positioned between the rim and inner tube in a manner that dulls an edge of the rim lip and, thereby, provides protection to the inner tube when compressed against the otherwise sharp edges of the rim lip.

Abstract: In a tube whose internal space is partitioned by a partition wall to formed an air chamber filled with air and a sealant chamber filled with a sealant, the ratio R (R=B/A) of the length B of an outer circumference of the tube accommodated in the tire and expanded by filling of air to the length A of an outer circumference of the tube in an unexpanded is set in a range of 100% to 110%. Thus, the tension of the partition wall at the time when the tube has been expanded is suppressed to a small extent. Even if the partition wall of the tube gets a punctured wound, the partition wall having only a small tension applied thereto has a weak tendency to be intended to be contracted toward the air chamber. Therefore, little, if any, of the air in the air chamber flows into the sealant chamber and thus, a reduction in sealing performance of the sealant due to the mixture with the air is prevented.

Abstract: A vehicle tire wheel has a tire (31) and a rim (32) with elastic members (39) formed on left and right side flange pares (37). The tire (31) is mounted to the rim (32) so that the elastic members (39) cone in contact with left and right side bead parts (35) of the tire (31). The elastic members reduce undesirable force exerted on the left and right side bead parts (35) from the rim (32).

Abstract: The present invention concerns an improvement in securing a tire stem assembly. Specifically, a rubber packing piece, washer and securing nut-containing rubber packing piece are employed in this assembly, which cause the tire stem to bind tightly to the hub when the inner tube is inflated. The merit is that air cannot escape quickly from the space between the stem and the hub when the inner tube of a tire is punctured by a sharp object, thereby allowing the motor-driven vehicle to continue to operate.

Abstract: A flap for tires has lateral wings at the ends of which there is an extension which, in stress-free condition, is spaced axially inwards from the inner wall of the tire so that, upon inflation, the inner tube first of all protrudes towards the inside of the inflatable cavity before it is flattened against the tire.
