| 中文摘要: |
| 综合分析了美国当前市场轮胎高宽比等结构参数的现状，指出:轮辋直径大的，轮胎高宽比取较小值.70.60 和75系列的轮胎规格的相对频数较高，三者相对频数之和达72; 美国市场轮胎的速度级别高的较多.S级及其以上的接近2/3. 轮胎速度级别也与轮辋直径有关，轮辋直径小的，最高速度级别较低，轮辋直径增大，轮胎的最高速度级别提高。 |
| 英文摘要: |
| An analysis of the tire structure parameters， such as aspect ratio， in the American tire market has been made. It is pointed that the smaller aspect ratios are taken for the rims with larger diameter;the 70， 60 and 75 series tires are at higher relative frequencies， and these three
frequencies sumed to 72; there are more high speed rated tires in American market， and two thirds of tires are S rated or above; the tire speed rating is relative to the rim diameter， i. e. the maximum tire speed rating is lower for the rim with smaller diameter， and the maximum tire speed rating raises as the rim diameter increases. |
