摘要： A run-flat tire capable of reducing weight and enhancing its uniformity. The run-flat tire 1 provides a toroidal carcass 6 extending from a tread portion 2 to the bead core of each bead portion 4 through each of sidewall portions 3 and a pair of side reinforcing rubbers 9 arranged inside the carcass 6 and extending along the sidewall portions 3 in the tire radial direction inwardly and outwardly. In the outer surface of the tread portion 2, pattern elements are arranged, thereby forming a pitch pattern. Each of the side reinforcing rubber 9 provides with recesses 11 circumferentially spaced on the inner surface of side reinforcing rubber facing the tire cavity. The total number (n) of recesses 11 on each of the side reinforcing rubber 9 is 0.70 to 1.30 times the total number of pattern elements.

摘要： A tire noise reducing system includes a wheel rim, a pneumatic tire mounted on the wheel rim to form an annular tire hollow, and a resonance damper disposed in the annular tire hollow, wherein the damper is one of an annular elastic loose band disposed around the rim and a flexible slack strip having a certain length and fixed to the wheel rim at two points so that a portion between the fixed points slacks, whereby a loose portion of the loose band and the slack portion of the slack strip are risen by a centrifugal force during running to at least partially block the annular tire hollow.

摘要： A tire noise damper to be disposed in an annular tire cavity formed between a wheel rim and a pneumatic tire mounted thereon. The damper comprises an annular band-like body which is made of an elastomeric material and provided with at least one generally U-shaped cut oriented in a circumferential direction. The cutout formed by the at least one U-shaped cut forms a flap risen by a centrifugal force during running, and the remainder forms a base band to be put around a bottom of the wheel rim in an elongated condition. In order to reduce resonance of the air in the tire cavity in not only the fundamental mode but also the higher harmonic modes, the flap may have a relatively long length such that, when risen, a radially outer end portion thereof comes into contact with the radially inside of a tread portion of the tire. Further, the flap may be made of nonwoven fabric at least partially.

摘要： A vehicle tire which has an aspect ratio of less than about 55% and comprises a tread portion having a profile whose radius of curvature decreases substantially continuously from the tire equator to each tread edges. The tread profile from the tire equator to each tread edge is substantially defined by a curve such as ellipse, cycloid, epicycloid, involute curves and the like, of which equation is differentiable in the range between the tire equator and each tread edge.
