Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 2983-2008 "Series of motorcycle tyres".
Compared with GB/T 2983-2008, the main technical changes are as follows.
- ADD the definitions of centrifugal radius and rolling radius (see 3.1 and 3.2);
- Delete the provision that the small-diameter tyres for code-designated
series motorcycle tyres are not suitable for off-road operations, such as
transportation (see 4.1 of the 2008 edition);
- Delete the provision that the maximum speed of small-diameter tyres for
metric series motorcycle tyres is 120 km/h (see 4.2 of the 2008 edition);
- ADD the additional mark indication method for the load index and speed
symbol of the moped tyres; ADD the load index value of each specification
(see 5.3 and Table 10, Table 11);
- ADD centrifugal radius and rolling radius as use reference dimensions (see
6.5 and Appendix C);
- ADD a total of 5 new specifications, 3.60-18, 4.60-17, 2.75-8, 3.75-12, and
5.00-12, to the motorcycle tyres of code-designated series; ADD 5
reinforced and 4 heavy-duty varieties to the previous specifications (see
Table 1 and Table 2);
- For the last sentence of the footnote “a” for the new tyre design section
width in specification parameter tables of the metric series motorcycle tyres,
modify it to “For tyres with a tread that is wider than its section width, the
total tread width is designated as the section width. And it shall not be less
than its minimum design section width value.” So that it is applicable to
tread profiles other than Type A; and also applicable to the code-designated
series (see Table 1, Table 2, Table 5, Table 6, and Table 7; Table 5, Table 6,
and Table 7 of the 2008 edition);
- Modify the outer diameter design and manufacturing tolerance factor of the
footnote "b" in specification parameter tables for the motorcycle tyres of
code-designated series and metric series; ADD the selected values of
tolerance factor for different tread patterns (see Table 1, Table 2, Table
5~Table 7; Table 1, Table 2, Table 5~Table 7 of the 2008 edition);
- ADD the value regulation of "taking the integer value according to GB/T
8170" when calculating the tyre dimension tolerance, to the footnotes of all
tyre specification parameter tables (see Table 1, Table 2, Table 5, Table 6,
Table 7, Table 10 and Table 11);
- ADD the applicable rims for the nominal section width 3.60 and (small-
diameter) 3.75, 5.00 in motorcycle tyres of code-designated series (see
Table 3 and Table 4);
- ADD the nominal aspect ratios of 30, 35 and 75 for metric series motorcycle
tyres (nominal rim diameter of 13~24); and, supplement 27 new
specifications (see Table 5 and Table 6);
- ADD 9 new specifications of metric series motorcycle tyres (nominal rim
diameter of 8~12) (see Table 7);
- ADD the applicable rims for 9 new nominal section widths in the metric
series motorcycle tyres (see Table 8);
- ADD the parameters for nominal rim diameters of 11, 20M/C, 23M/C and
24M/C (see Table 14);
- ADD 17 tyre design section height values corresponding to the newly-added
nominal section widths (see Table 15);
- Modify the division of tread patterns of motorcycle tyres to no longer being
limited to the previous metric series; redefine the scope of application (see
Appendix A; Appendix A of the 2008 edition);
- ADD speed symbol Y (see Table B.2);
- For the load-carrying change rate of tyres with different speeds of ≤150
km/h, add the applicable symbols and related instructions (see Table B.3).
This Standard uses the redraft law to refer to ISO 4249-1.1985 “Motorcycle
tyres and rims (code-designated series) - Part 1.Tyre”, ISO 4249-2.1990
“Motorcycle tyres and rims (code-designated series) - Part 2.Tyre load ratings”,
ISO 4249-3.2010 “Motorcycle tyres and rims (code-designated series) - Part 3.
Rims”, ISO 5751-1.2010 “Motorcycle tyres and rims (metric series) - Part 1.
Design guides”, ISO 5751-2.2010 “Motorcycle tyres and rims (metric series) -

contours”, ISO 5995-1.1982 “Moped tyres and rims - Part 1.Tyres”, and ISO
6054-1.1994 “Motorcycle tyres and rims (code-designated series) - Diameter
codes 4 to 12 - Part 1.Tyres” for preparation. The degree of consistency with
them is non-equivalent.

Federation.

Centrifugal radius
The allowable maximum dynamic radius of tyre expansion under the action of
centrifugal force when the high-speed motorcycle tyre is running at its highest
