ISO/TC 31/SC 10 - Cycle, moped, motorcycle tyres and rims

This document specifies test methods for verifying the capabilities of tyres for motorcycles. Of the test methods presented, only some can be required depending on the type of tyre to be tested. The tests are carried out in the laboratory under controlled conditions. This document includes a strength test for assessing the capability of the tyre structure, with respect to breaking energy. A second test, the endurance test, assesses the resistance of the tyre with respect to service at full load and moderate speed over long distances. The third test, the high-speed test, assesses the capability of the tyre as related to service at the maximum speed capability of the tyre. The centrifugal growth test assesses the maximum growth of the tyre under the influence of centrifugal forces at the maximum speed capability of the tyre. The test methods presented in this document are not intended for gradation of tyre performance or quality levels. This document is applicable to all motorcycle tyres.

ISO 29802:2017 specifies the designations, dimensions, markings and load ratings of pneumatic tyres primarily intended for all-terrain vehicles (ATV). It also specifies the designation, marking and contours of rims. The tyres meet the following parameters: a) speeds not exceeding 130 km/h (Speed Symbol M); b) fitted to (AT) 5° tapered drop centre rims; c) nominal rim diameter codes of 7 to 14 inclusive.

ISO 5751-1:2010 gives guidelines for the design of, and specifies the designation and calculation of the dimensions for metric series motorcycle tyres. It is applicable to motorcycle tyres with a reduced height/width ratio (100 and lower) that can be fitted on cylindrical bead-seat or 5° tapered bead-seat rims. It is also applicable to other concepts of tyre and rim, provided the appropriate rim/section ratios and coefficients are established for them.

This International Standard specifies a method for measuring the rolling circumference and revolutions per unit distance (kilometre) for new tyres, under loaded conditions, made for use on motorcycles and mopeds. The values obtained according to this method are not intended for use as levels of performance or quality. This International Standard is applicable to all motorcycle and moped tyres designed and intended for use on the road. NOTE Since most speedometers and odometers on motorcycles are activated from the front wheel, the test tyres will largely fall into sizes applicable for front wheel use. However, it is accepted that rear tyres will also be measured.

Cancels and replaces the second edition (1990). Lays down the designation, dimensions, and load ratings for an inch-code-designated series of tyres for motorcycles, fitted on rims with a nominal diameter corresponding to the codes 4, 5, 6, 7, 8, 9, 10 and 12. The requirements for rims are described in ISO 6054-2.

This second edition cancels and replaces the first edition (1983).

This second edition cancels and replaces the first edition (1978). This part sets out the designation in use and the dimensions for an inch code designated series of tyres.

ISO 5775-2:2015 specifies rim dimensions for bicycle tyres: it gives only those rim contour dimensions necessary for tyre mounting and to fit the tyre on the rim. ISO 5775‑1 covers designations and dimensions for tyres. ISO 5775‑2 covers straight side (SS) rims, hooked bead type (HB) rims and crotchet type (C) rims.

ISO 29802:2009 specifies the designations, dimensions, markings and load ratings of pneumatic tyres primarily intended for all terrain vehicles (ATV). It also specifies the designation, marking and contours of rims. The tyres are based on the following parameters: speeds not exceeding 130 km/h (speed symbol M); fitted to (AT) 5° tapered drop centre rims; nominal rim diameter codes of 7 to 14 inclusive.

ISO 5751-1:2004 gives guidelines for the design of, and specifies the designation and calculation of the dimensions for, metric-series motorcycle tyres. It is applicable to motorcycle tyres with a reduced height/width ratio (100 and lower) that can be fitted on cylindrical bead-seat or 5° tapered bead-seat rims. It is also applicable to other concepts of tyre and rim, provided the appropriate rim/section ratios and coefficients have been established for them.

The tests include a strength test for assessing the capability of the tyre structure with respect to breaking energy in the tread area, an endurance test for assessing the resistance of the tyre with respect to service at full load and moderate speed over long distances, a high-speed test for assessing the capability of the tyre as related to service at the maximum speed capability of the tyre (not applicable to tyres with a speed capability below 130 km/h), and a centrifugal growth test for assessing the maximum growth of the tyre under the influence of centrifugal forces at the maximum speed capability of the tyre (applicable only to road tyres with speed symbols P and above). ISO 10231:2003 is applicable to all motorcycle tyres. However, its test methods are not intended for gradation of tyre performance or quality levels.
