Full title and description

ISO 10231:2025 — Motorcycle tyres — Test methods for verifying tyre capabilities. This International Standard specifies laboratory test methods to verify the capability and structural behaviour of motorcycle tyres; the methods are intended for verification and assessment rather than for grading or performance classification.

Abstract

The standard defines laboratory procedures to verify tyre capability. It includes methods used to assess structural strength and service performance under specified conditions; earlier and related editions describe specific strength, endurance, high‑speed and centrifugal‑growth tests which are retained or updated in the 2025 edition. The test methods are not intended for performance grading and apply to all motorcycle tyres.

General information

• Status: Published
• Publication date: 20 May 2025.
• Publisher: International Organization for Standardization (ISO)
• ICS / categories: 83.160.10 (Tyres and wheels)
• Edition / version: Edition 5 (2025)
• Number of pages: 11.

Scope

Specifies test methods for verifying the capabilities of motorcycle tyres. The methods are performed in laboratory conditions and are intended to demonstrate capability of tyre structure and service behaviour (strength, endurance and behaviour at maximum speed) rather than to provide a graded performance ranking. The document is applicable to all categories of motorcycle tyres.

Key topics and requirements

• Laboratory test methods for verification of motorcycle tyre capabilities.
• Structural strength (breaking-energy) test requirements and procedures.
• Endurance test methods for long‑distance service at full load and moderate speeds.
• High‑speed test procedures to assess behaviour at maximum speed capability.
• Centrifugal‑growth test to determine tyre growth under centrifugal forces.
• Requirements on test conditions, instrumentation and reporting to ensure repeatability and comparability.
• Statement that tests are for capability verification and not for performance grading.

Typical use and users

Used by motorcycle‑tyre manufacturers, independent testing laboratories, vehicle and tyre certification bodies, motorcycle OEMs (original equipment manufacturers), R&D departments and national/regional regulators to verify tyre designs, demonstrate compliance with required capability criteria and support type‑approval or internal quality assurance processes.

Related standards

Successor to earlier editions of ISO 10231 (1992, 1997, 2003 and the 2022 edition which has been withdrawn and revised by the 2025 edition). National/adopted versions (for example BS ISO 10231:2025) provide the same content as the ISO international publication.

FAQ

Q: What is this standard?

A: ISO 10231:2025 is an International Standard that specifies laboratory test methods to verify the capabilities of motorcycle tyres (structural and service behaviour).

Q: What does it cover?

A: It covers procedures and requirements for tests used to verify tyre capability (including structural strength, endurance, high‑speed behaviour and centrifugal growth), the test conditions, measurement and reporting necessary to produce repeatable verification results.

Q: Who typically uses it?

A: Tyre manufacturers, independent testing laboratories, motorcycle OEMs, certification bodies, regulatory agencies and R&D teams use the standard to verify tyre designs and demonstrate capability for approval and quality assurance.

Q: Is it current or superseded?

A: Current — ISO 10231:2025 was published in May 2025 and replaces the previous ISO 10231 editions (the 2022 edition was withdrawn and superseded by this 2025 edition).

Q: Is it part of a series?

A: ISO 10231 is a standalone standard focused on motorcycle-tyre test methods; it exists in multiple editions over time and is related by subject matter to other ISO and national standards addressing tyres, wheels and vehicle tyre testing procedures.
