10、/4 and partially supersedes BS AU 50-2.1c:1980, which is withdrawn. It is identical with ISO 4209-2:1993, Truck and bus tyres and rims (metric series) Part 2: Rims, published by the International Organization for Standardization (ISO). Other Parts of this standard are: Part 2: Wheels and rims; Part
11、3: Valves; Part 4: Rim profiles and dimensions. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obliga
12、tions. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 5 and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

14、sions of rims primarily intended for trucks and buses. Tyre designations, dimensions and load ratings are given in ISO 4209-1. This part of ISO 4209 specifies the designations, contours and dimensions of drop-centre (one-piece) rims. The rim dimensions are those rim contour dimensions necessary for
15、mounting and fitment of the tyre to the rim. 2 Designation and marking The rim shall be designated by its nominal rim diameter code and nominal rim width (for example 17.5 5.25), and rim flange when specified (for example: 15 6 J : 13 5.50 B). 3 5 tapered (drop-centre) rims 3.1 Rim flange Rim flange
