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.

摘要： A tire noise damper to be disposed in an annular tire hollow formed between a wheel rim and a pneumatic tire mounted thereon, the damper made of a flexible material and comprising a base to be secured to the wheel rim and at least one flap extending from the base to be risen radially outwards from the wheel rim by centrifugal force during running to block the annular tire hollow. For example, the damper comprises at least one annular elastic band to be put around the wheel rim, the annular band provided with at least one U-cut for forming a flap, and the base is formed by the remaining annular portion of the band. In another example, the damper is made of a strip of the fixable material having a certain length, the base is formed by one end portion of the strip, and the flap is formed by the remaining portion of the strip.

摘要： A tread pattern of tire tread is formed by an alignment (sequence) of pattern composing units of s types different in pitch P that is a circumferential length. The pattern composing units are allocated to sections of the axes of abscissa and ordinate from the origin in the order of lower pitch P. Out of all regions present in a certain section of the axis of abscissa and aligned in the longitudinal direction, a defined region defining a chaotic function is determined for respective sections of abscissa. The chaotic function is represented by X(n+1)=fc(Xn), where Xn is the axis of abscissa, and X(n+1) the axis of ordinate. An alignment of pattern composing units is obtained according to a sequence of numbers sequentially obtained by the chaotic function. The alignment of pattern composing units is further verified before employment. In such manner, discomfort due to noises caused by a tire during a travel is reduced.
