Full title and description

ISO 10231:2022 — Motorcycle tyres — Test methods for verifying tyre capabilities. This international standard specifies laboratory test methods (strength, endurance, high‑speed and centrifugal growth) used to verify the structural and service capabilities of motorcycle tyres; the methods are intended for verification under controlled conditions and are not for grading tyre performance levels.

Abstract

Provides repeatable, instrumented test procedures to assess tyre breaking energy (strength test), long‑distance service resistance under load and moderate speed (endurance test), behaviour at maximum rated speed (high‑speed test) and maximum radial growth due to centrifugal forces (centrifugal growth test). Applicability of individual tests depends on tyre construction and intended speed/load ratings.

Scope

Applies to all motorcycle tyres for which verification of capability in laboratory conditions is required. The document defines which of the four principal tests (strength, endurance, high‑speed, centrifugal growth) are relevant for a given tyre type and specifies test apparatus, conditioning, test sequences, speeds, loads and acceptance observations for verification purposes. The standard does not set performance grading levels; it provides verification test methods only.

Key topics and requirements

• Strength test to determine tyre breaking energy and structural capability (note: some tests may be inapplicable to certain constructions such as some radial tyres).
• Endurance (fatigue) test protocol for long‑distance service at specified load and moderate speed, including conditioning and temperature control.
• High‑speed test procedure to verify tyre behaviour at its maximum speed capability, including speed profiles, load conditions and run‑out tolerances.
• Centrifugal growth measurement to record maximum radial growth at maximum speed capability and define measurement apparatus/technique.
• Detailed specifications for test equipment, e.g. drum diameters, plunger geometry, instrumentation tolerances and inflation measurement accuracy.
• Applicability rules and exclusions (which tests apply to which tyre constructions and speed/ load classes).

Technical detail and typical values for equipment and tolerances are given in the standard text; the above list summarizes the main topical requirements.

Typical use and users

Used by tyre manufacturers, independent test laboratories, motorcycle OEMs, certification and homologation authorities and regulatory bodies to verify that motorcycle tyres meet specified capability requirements under controlled laboratory conditions. Also referenced by quality and compliance teams when validating tyre designs and production batches prior to market release.

Related standards

Replaces earlier ISO 10231 editions/amendments (for example ISO 10231:2003 and ISO 10231:2003/Amd 1:2015) and has been recorded in ISO lifecycle records as withdrawn and superseded by a later revision (ISO 10231:2025). For terminology and definitions the standard references related ISO documents such as ISO 4223‑1 (terminology for road vehicles/motorcycles).

FAQ

Q: What is this standard?

A: ISO 10231:2022 is an international standard that specifies laboratory test methods for verifying the capability of motorcycle tyres (strength, endurance, high‑speed and centrifugal growth).

Q: What does it cover?

A: It covers test procedures, required equipment and tolerances, conditioning and test sequences used to verify tyre structural strength, service endurance, behaviour at maximum speed and centrifugal growth. It is for verification only and does not provide performance grading.

Q: Who typically uses it?

A: Tyre manufacturers, independent test laboratories, motorcycle OEMs, homologation and regulatory agencies, and compliance/QA teams use the standard to verify tyre capability in controlled laboratory conditions.

Q: Is it current or superseded?

A: The 2022 edition is recorded as withdrawn in ISO lifecycle records and has been superseded by a later revision recorded as ISO 10231:2025. Users should consult the most recent ISO catalogue entry or national standards bodies for the current active text.

Q: Is it part of a series?

A: ISO 10231 is a stand‑alone test‑methods standard for motorcycle tyres but references other ISO documents for terminology and related technical matters; it has multiple historical editions and amendments and is part of the broader family of tyre and vehicle standards maintained by ISO/TC 31 and its subcommittees.

Q: What are the key keywords?

A: Motorcycle tyres, tyre testing, strength, endurance, high‑speed, centrifugal growth, verification, tyre capability, ISO 10231.
