Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted
by the technical committees are circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 5751 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 5751-2 was prepared by Technical Committee ISO/TC 31, Tyres, rims and valves, Subcommittee SC 10,
Cycle, moped, motorcycle tyres and rims.
This fourth edition cancels and replaces the third edition (ISO 5751-2:1994), which has been technically revised.
ISO 5751 consists of the following parts, under the general title Motorcycle tyres and rims (metric series):
— Part 1: Design guides
— Part 2: Tyre dimensions and load-carrying capacities
— Part 3: Range of approved rim contours

code 12 and below.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of

3 Terms and definitions
For the purposes of this part of ISO 5751, the terms and definitions given in ISO 4223-1 apply.
4 Tyre designation
4.1 General
The tyre designation shall be as specified in ISO 5751-1, completed by the addition of the service description, i.e.
load index and speed symbol.

ISO 5751-2:2002(E)
4.2 Tyre construction code
The tyre construction code shall be as follows:
 “-” for diagonal-ply tyres;
 “B” for bias-belted tyres;
 “R” for radial-ply tyres.
NOTE For tyres suitable for speeds greater than 240 km/h, see ISO 5751-1.
4.3 Marking — Example
A motorcycle tyre having
a) a size and construction of
 nominal section width of 100 mm,
 nominal aspect ratio 90, and
 nominal rim diameter code 18, with
b) a service description consisting of
 load-carrying capacity, 224 kg (corresponding to load index 56), and
 reference speed, 150 km/h (corresponding to speed symbol P),
shall be marked, respectively, as follows:
if in diagonal-ply construction 100/90 – 18M/C 56 P
if in bias-belted construction 100/90 B 18M/C 56 P
if in radial-ply construction 100/90 R 18M/C 56 P
4.4 Other markings
For nominal rim diameter codes 13 and above, the suffix “M/C” shall be added to the size and construction
marking, after the nominal rim diameter code. For tyres having a nominal rim diameter code 16 and higher, this
marking is not required before May 2003.
Extra-load version tyres shall be additionally marked either “Extra Load” or “REINF” (for “reinforced”).
5 Tyre dimensions
5.1 General
Tables 1 to 10 show
a) the tyre size designation,
b) the measuring rim width code,
2 © ISO 2002 – All rights reserved

---------------------- Page: 6 ----------------------
ISO 5751-2:2002(E)
c) the design tyre dimensions, i.e. section width and overall diameter, and
d) the maximum tyre dimensions in service, i.e. overall width and diameter for the various types of tread
configurations (see clause 7) to be considered by vehicle manufacturers in designing for tyre clearances.
NOTE The maximum dimensions in service do not include the values of the centrifugal radius (see ISO 5751-1).
5.2 Measurement method
Mount the tyre on a rim chosen according to ISO 5751-3, approved for the respective tyre size, ready for fitting and
with the tyre inflated as follows.
a) For normal-load version tyres:
 225 kPa for speed symbols S and lower;
 280 kPa for speed symbols T and higher.
b) For extra-load version tyres:
 280 kPa for speed symbols P and lower;
 330 kPa for speed symbols Q and higher.
c) For light-load version tyres: 175 kPA.
Allow the tyre to stand for 24 h at normal room temperature, then readjust the inflation pressures to those specified
above, before performing the measurements.
When performing measurements on rims having a rim width code differing from that of the measuring rim width
code given in the tables of this part of ISO 5751, the section-width and overall-width values of the tyre shall be
adjusted according to the formula:
W = W + 0,4 (R − R )
m m
where
W is the value measured;
m
R is the width, in millimetres, of the rim used for the measurements;
m
R is the width, in millimetres, of the measuring rim width code given in the tables.
6 Tread configurations
Figure 1 of ISO 5751-1:— shows various tread configurations. These attributions of tread type configurations to the
service are to be considered as examples only. The choice of a given tread type configuration for a given tyre
depends on the tyre manufacturer alone.
 Tread type A is commonly adopted for highway-service low-speed tyres.
 Tread type B is commonly adopted for highway-service high-speed tyres.
 Tread type C is commonly adopted for tyres used in on- and off-road service.
 Tread type D is commonly adopted for tyres exclusively in off-road service.

7 Load ratings
7.1 General
Tables 11 to 21 show the maximum tyre load-carrying capacity referred to the load index.
7.2 Load capacity at reduced speeds
Subject to acceptance by the tyre manufacturer and taking into account the conditions of use of the motorcycle, the
load capacities corresponding to the load indices indicated in Tables 11 to 21 may be modified according to the
percentage shown in Table 22. This modification is possible when the motorcycle maximum speed is different from
the one associated with the speed symbol.
7.3 Load capacity at speeds higher than 210 km/h
For the load carrying capacities of tyres marked with speed symbols “V” or “W” operating at speeds higher than
210 km/h, see ISO 5751-1.
8 Inflation pressures
The following inflation pressures are guidelines only. Inflation pressures used in practice are subject to agreement
between the tyre and vehicle manufacturers and should take into account not only the load, but also the tyre
construction, road-holding, maximum speed, location of the tyre, operating conditions and mechanical
characteristics of the vehicle.
The maximum load-carrying capacity is in reference to the following inflation pressures.
a) For nominal rim diameter codes up to and including 12 (for series 80 and above):
1) light-load version — 175 kPa;
2) normal-load version — 250 kPa;
3) extra-load version — 300 kPa.
b) For nominal rim diameter codes 13 and above (for series 70 and below, also applicable to nominal rim
diameter codes 12 and below):
1) light-load version — 175 kPa;
2) normal-load version
 for tyres marked with a speed symbol up to and including P — 225 kPa,
 for tyres marked with speed symbol Q, R or S — 250 kPa,
 for tyres marked with speed symbol T, U or H — 280 kPa, and
 for tyres marked with speed symbol V or W — 290 kPa;
3) extra-load version tyres — these inflation pressures are to be increased by 50 kPa.
