Overview

ISO 10571:2024 - “Tyres for mobile cranes and similar specialized machines” defines designation, dimensions, load ratings and reference speeds for tyres and rims fitted to vehicles (for example all‑terrain equipment, mobile cranes and crash tenders) that are likely to operate on public roads over long distances at a reference speed under constant load. This fourth edition updates tyre and rim tables, adds definitions (road, driving on the road, creep, stationary) and clarifies service markings and load/speed relationships for crane tyres.

Key topics

• Tyre designation and marking: Mandatory sidewall information includes nominal section width, aspect ratio, construction code (radial “R” or dash for bias), rim diameter code, load index and speed symbol (E = 70 km/h, F = 80 km/h). Optional regional markings include “ROAD” service ID and Load Range.
• Dimensions and series: Design and in‑service dimensions are provided for common series (notably 95 and 80 series tyres), including measuring rim width, section width and overall diameter.
• Load ratings and speed interaction: Tables map load index to tyre load‑carrying capacity (TLCC) and define basic tyre loads at reference speeds. Important: E and F speed‑rated tyres are not interchangeable because their load capabilities at the same speed differ.
• Load range and inflation: Correlation of load range to reference inflation pressure is specified (e.g., Load Range L → 700 kPa, N → 900 kPa) - regional options may apply.
• Approved rims and contours: Approved rim contours and references to rim dimension standards (ISO 4250‑3) are included.
• Other markings: Requirements for “TUBELESS”, preferred rotation arrows and optional “RADIAL” wording.

Applications

• Tyre manufacturers: design, label, certify and publish load/speed tables for crane tyres and approved rim combinations.
• Crane OEMs and fleet specifiers: select tyres and rims that meet load, speed and dimensional requirements for on‑road and mixed‑use machines.
• Fleet managers & procurement: ensure correct tyre selection (load index, speed symbol, inflation) to comply with safety, regulatory and warranty requirements.
• Test laboratories & certification bodies: verify tyre marking, load capacity, rim compatibility and conformity with ISO 10571:2024.
• Regulators and standards committees: reference for national regulations and for alignment with related documents (ISO 17253 for machinery, ISO 4223‑1 for definitions).

Related standards

• ISO 17253 - machinery types referenced in the introduction
• ISO 4209‑1 - truck and bus tyres and rims (metric series)
• ISO 4223‑1 - tyre industry definitions
• ISO 4250‑3 - earth‑mover rims (rim dimensions and codes)
• ISO 3877‑1 - equivalent tyre industry terminology

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

This document was prepared by Technical Committee ISO/TC 31, Tyres, rims and valves, Subcommittee SC 6,
Off-the-road tyres and rims.
This fourth edition cancels and replaces the third edition (ISO 10571:2016), which has been technically
revised.
The main changes are as follows:
— reference to ISO 17253 was added to the Introduction;
— definitions of road (3.1), driving on the road (3.2), off the road use (3.3), creep (3.4), and stationary (3.5)
were added;
— 4.3: ‘road use’ was replaced by ‘driving on the road’;
— Table 10 and Table 12 were added; all following tables were renumbered accordingly;
— in Tables 3, 5, and 13, 325/95R24 was added;
— in Table 5, 505/95R25 183E Load Range M was added;
— Table 13 (rims) was revised; rim 15.00/3.5 was replaced by 15.00/3.0 for 575/95R25.
Any feedback or questions on this document should be directed to the user’s national standards body. A
