    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 vehicle wheel adapted to provide support for deflated or punctured tire. The wheel rim comprises a pair of parallel, circumferentially extending, axially spaced-apart, radially outwardly facing bead seats. Adjacent to and axially outwards of each bead seat is a radially outwardly projecting tire retaining flange. A tire fitting well is provided between the bead seat and a substantially rigid, deflated tire support surface radially outwardly of the bead seats mounted upon a support member projecting radially from the well wherein the support member is positioned at one side of the well, considered in axial cross section of the wheel rim, around part of the circumference of the wheel rim and at the other side of the well around the remainder of the circumference so that tire fitting is facilitated. The support member is preferably at one side of the well around half the circumference and may also be integral and the remainder of the wheel rim.

    Abstract translation: 适用于为放气或穿孔的轮胎提供支撑的车轮。 轮辋包括一对平行的，周向延伸的，轴向间隔开的径向向外的胎圈座。 每个胎圈座的邻近和轴向向外是径向向外突出的轮胎保持凸缘。 轮胎配合孔设置在胎圈座和径向向外安置在从井径向突出的支撑构件上的胎圈座的基本上刚性，放气的轮胎支撑表面中，其中支撑构件位于井的一侧， 轮缘的轴向横截面，围绕轮缘的圆周的一部分，以及围绕圆周的其余部分的井的另一侧，从而便于轮胎装配。 支撑构件优选地位于围绕圆周的一半的井的一侧，并且还可以是一体的，并且轮缘的其余部分。
