Foreword
This document was drafted in accordance with the rules given in GB/T 1.1-2020
"Directives for standardization - Part 1: Rules for the structure and drafting of
standardizing documents".
This document replaces GB/T 3487-2015 "Rims for passenger car". Compared with
GB/T 3487-2015, in addition to structural adjustments and editorial changes, the main
technical changes in this document are as follows:
- Changed the layout of the diagrams, unifying the right side as the tire installation
side (see Figure 1, Figure 2 of this Edition; Figure 1, Figure 2 of Edition 2015);
- Modified the provisions of the "Snap-on valve hole" section (see 5.4.2 of this
Edition; 5.4.2 of Edition 2015);
- Added relevant provisions for "Compression-type valve hole" (see 5.4.3 of this
Edition).
The modification of this document adopted ISO 4000-2:2021 "Passenger car tyres and
rims -- Part 2: Rims".
Compared with ISO 4000-2:2021, this document has more structural adjustments. See
Annex A for a comparison of the structural number changes between the two documents.
The technical differences between this document and ISO 4000-2:2021 and their
reasons are as follows:
- ISO 3911 (see Chapter 3 of this document) was replaced by the normative reference
GB/T 2933 to adapt to China's technical conditions;
- The normative reference ISO 9413 (see Chapter 3 of this document; Table 5 in ISO
4000-2:2021) has been deleted, and the relevant content has been deleted;
- Added "Rim profile size code" and its illustration (see Chapter 4 of this document)
for ease of use;
- Deleted rim specifications and marking (see Chapter 4 of ISO 4000-2:2021) as
their contents are already specified in the referenced standards;
- The footnotes of the snap-on valve hole dimension drawing have been changed
(see the footnote of Figure 4 of this document; the footnote of Figure 3 in ISO
4000-2:2021). Figure 4 has been deleted because this provision in ISO 4000-
2:2021 is incorrect;
- The illustration of the compression valve hole dimensions has been changed (see
Figure 5 of this document; Figure 5 of ISO 4000-2:2021). Dimension d (see Table
