        輪胎規格

        作者: Admin 來源: 發布時間: 18-08-03

        輪胎規格
        輪胎規格常用一組數字表示,前一個數字表示輪胎斷面寬度,后一個表示輪輞直徑,以英寸為單位。例如165/70R14表示胎寬165毫米,扁平率70,輪輞直徑14英寸。中間的字母或符號有特殊含義:“X”表示高壓胎;“R”、“Z”表示子午胎;“一”表示低壓胎。

        層級
        層級是指輪胎橡膠層內簾布的公稱層數,與實際簾布層數不完全一致,是輪胎強度的重要指標。層級用中文標志,如12層級;用英文標志,如“14P.R”即14層級。

        輪輞規格
        表示與輪胎相配用的輪輞規格。便于實際使用,如“標準輪輞5.00F”。

        速度等級
        輪胎在規定條件承載規定負荷的最高速度。字母A至Z代表輪胎從4.8km/h到300km/h的認證速度等級。常用速度等級:Q:160km/h;R:170km/h;S:180km/h;T:190km/h;H:210km/h;V:240km/h;W:270km/h;Y:300km/h;Z:ZR速度高于240km/h。
