Abstract: A vehicle's spare tire can be made lighter and cheaper for economy, but this entails limited performance and shorter safe life. The invention provides a temporary spare tire with a tread which emits a distinctive two-tone or three-tone warning sound when in use to give audible warning of the need for early replacement.The tread is structured to maximize highway noise, and is circumferentially divided into two or more parts, each at least one-sixth of the circumference and which contact the highway in sequence. Each part emits a particular different note or tone, so that different notes or tones sound in sequence as the vehicle moves. The preferred tread structure is a block pattern with a sinusoidally varying land/sea ratio to concentrate acoustic energy at a characteristic frequency within each circumferential part. The same tread pattern may be used around the whole tread, "stretched" into long-pitch lengths for low notes and "compressed" into short-pitch lengths for high notes.

Abstract translation: 一辆车的备用轮胎经济可以做得更轻，更便宜，但这样做的结果是有限的性能和更短的安全寿命。 本发明提供了一种具有胎面的临时备胎，其在使用时发出独特的双音或三音警报声，以提供对早期更换需要的可听见的警告。 胎面的结构是使公路噪声最大化，并且周向地分为两个或更多个部分，每个部分至少有六分之一的圆周，并且与高速公路顺序接触。 每个部分发出特定的不同音符或音调，使得当车辆移动时，不同的音符或音调依次发音。 优选的胎面结构是具有正弦变化的陆/海比以将每个圆周部分内的特征频率处的声能集中的块图案。 可以在整个胎面周围使用相同的胎面花纹，“拉伸”为长节距，用于低音，并且“压缩”成高音调的短节距。

Abstract: A tread configuration for pneumatic vehicle tires, particularly for spare tires, having a large number of depressions which are separated from each other by transverse webs and peripheral webs, and are successively arranged in the transverse and the peripheral directions of the tire. The depressions have an approximately rectangular cross section, and extend transverse to the peripheral direction of the tire. The webs which limit or define the depressions have a width corresponding to approximately 1/4 to 3/4 of the peripheral dimension of the depressions.

Abstract: A method is disclosed for evaluating the level of objectionable noise associated with the operation of a tire by virtue of its tread contacting a road surface, which comprises digitizing the tread design on a coordinate system so as to define load-supporting portions of the tread in contact with the pavement, and distinguish them in binary form from those portions of the tread which are not in contact, as multiple matrix elements; defining a generally arcuate profile of a leading or trailing edge of a footprint of the tread by fitting an equation to the edge; sequentially performing the time ensemble summation, of the noise produced by each matrix element, over every matrix element on the entire circumferential surface; converting the sequence of summation to a periodic analog signal; converting the analog signal to a sound; and, aurally evaluating the sound. In a simplified case 0's and 1's along at least one footprint edge are sequentially summed around the circumference of the tire. The system requires only a means for digitizing the tread pattern, a computer to perform the necessary manipulations of data, and a means to convert a digital signal to an analog signal. Having subjectively chosen a tread pattern deemed to have an acceptable noise level, ribs are then relatively rotated one with respect to another to obtain an improved level of tread noise.

Abstract: Noise generated by load supporting elements of an apparatus (e.g., tread of a tire) having a plurality of repeating design cycles is spread over a broad frequency spectrum. This is accomplished by designing load bearing elements in accordance with the following procedure.First, determining the maximum number of repeating design cycles which may be placed about the apparatus;Second, selecting a maximum pitch ratio;Third, determining the appropriate number of harmonic segments into which the apparatus can be divided;Fourth, determining the size of each of the harmonic segments and the number of design cycles for each of the harmonic segments;Fifth, arranging the various design cycles in each of the harmonic segments so that the wave length of the predominant modulation frequency of the segment corresponds to the fundamental length of that segment.

Abstract: A tire of the radial or crossing ply carcass type with an asymmetric tread reinforcement is improved due to the fact that a correction block is interposed between the assymetric tread reinforcement and the carcass reinforcement. This correction block consists of two plies of wires or cables which form with the longitudinal direction angles of opposite sign, each both other than zero and less than one-third of the smallest angle used in the asymmetric tread reinforcement. The correction block is preferably centered on the equatorial plane of the tire.
